A MONTHLY ANALYSIS OF CONSUMER DEMAND IN THE UNITED STATES AgEcon
Sexauer, Benjamin.
This study estimates monthly consumer demand equations for fifteen major commodities based on data for 1947-1972. The equations are estimated within the framework of the Nerlove partial adjustment model. By extrapolating from retail sales data, it was possible to generate the consumer expenditure data needed to combine with published monthly series on income and prices to estimate a series of consumer demand equations.

A new genus and two new species of the crustacean order Thermosbaebacea from the West Indies Naturalis
Stock, Jan H..
Up to now, the crustacean order Thermosbaenacea contained two genera with only six valid species, five from the panmediterranean region, one from Texas. Two new members of this curious group of “living fossils” have been discovered in the West Indies. The one, from two deep wells not far from the sea coast in Saint Croix (U.S. Virgin Islands), belongs to an undescribed species of the amphiatlantic genus Monodella, and is called M. sanctaecrucis. The other was found in several localities in Curaçao (Netherlands’ Antilles), in coral débris of rubble walls on the shore; it belongs to a new genus, Halosbaena showing several remarkable adaptations, e.g. having a uniramous first pereiopod and reductions in the maxilliped. The presence of very numerous...

A new member of the crustacean suborder Ingolfiellidea from Bonaire, with a review of the entire suborder Naturalis
Stock, Jan H..
A single specimen of an ingolfiellid was found in a slightly brackish well (locally called a “pos”) on the Bacuna estate in the island of Bonaire (Netherlands Antilles). The specimen differs from all other 21 ingolfiellid taxa, and is described as a new species, Ingolfiella (Gevgeliella) putealis. The two classification systems in use for the Ingolfiellidea, that of KARAMAN (1959) and that of RUFFO (1970), are compared and both are found not entirely satisfactory in the light of recent discoveries. A new system is devised, in which the suborder is divided into 2 families, together with 3 genera and 5 subgenera. The genera and subgenera do not only represent morphological unities, but also combine species with similar habitat requirements. Within the...

A new species of Tortricidae (Lepidoptera) from Madeira Naturalis
Diakonoff, A.; Wolff, N.L..
When studying the Microlepidoptera fauna of Madeira, the second author came across two puzzling big specimens of the Olethreutinae (Tortricidae): one, a male from the Staatssammlung für Naturkunde, Karlsruhe, Germany, another, a female, from the Naturhistorisches Museum, Wien, Austria. The two specimens appeared to belong to one and the same, sexually dimorphous, apparently new species which is described below. The holotype, ♂, will be deposited in the Karlsruhe Museum, the allotype, ♀, in the Vienna Museum. We are indebted to the authorities of the Karlsruhe and Vienna Museums for the kindness of entrusting this material to us for identification. The photographs of the genitalia have been made by Mr. Bent W. Rasmussen, Copenhagen Museum. Acroclita...

A nomenclatural correction in Caltha (Ranunculaceae) Naturalis
Keener, Carl S..
In a comprehensive treatment of Caltha, Petra Smit (Blumea 21: 119—150. 1973) unfortunately chose an incorrect name for her fourth variety under C. palustris L. Instead of var. radicans (Forst.) Beck, this taxon should be called C. palustris var. flabellifolia (Pursh) Torrey & Gray (Fl. N. Am. I: 27. 1838). Forster’s C. radicans was described in 1807 (Trans. Linn. Soc. 8: 324) and reduced to varietal status by Beck in 1886 (Verh. Zool. Bot. Gesellsch. Wien 36: 350). According to the current International Code of Botanical Nomenclature, no name has priority outside of its rank (cf. Art. 60). Inasmuch as C. palustris var. flabellifolia was the name first established for Smit’s variety d’, as such it has priority over C. palustris var. radicans (Forst.)...

A note on Aceratium ferrugineum C. T. White (Elaeocarpaceae) Naturalis
Balgooy, M.M.J. van.
When I revised the Australian species of Aceratium (van Balgooy, 1963) no good flowering material was available of A. ferrugineum. By then the species had only been collected four times, all in rainforest on Mt. Spurgeon and Mt. Lewis in NE Queensland. Although more material of this apparently rare Australian endemic has been collected since, no flowering material became available until November 28, 1974, when Bernie Hyland found a tree of this species in flower. He kindly sent me flowers preserved in F.A.A. for study and completion of my earlier description. The notes that follow are based mainly on this collection, B. P. M. Hyland 7885, State Forest Reserve 143, North Mary Logging Area, 16°30' S, 145°15'E, in rainforest at 1200 m, and on van Balgooy...

A NOTE ON FORMULATION OF PROPORTIONALITY RESTRAINTS IN LINEAR PROGRAMMING BLENDING PROBLEMS AgEcon
Filan, S.J..
A class of restraints on proportions is observed to be relevant in many applications of linear programming, but problem formulation for these restraints has received little attention in the literature. An approach reported by Taylor [5] is summarized, and an alternative approach is outlined. The alternative is equivalent to the first approach but provides simplicity in problem specification and economies in data preparation.

A NOTE ON THE ECONOMIC SURPLUS FROM DAIRY HERD RECORDING IN VICTORIA AgEcon
Ryan, Timothy J.; Badham, F.V..
An input demand model was used to estimate the own price elasticity of dairy herd recording in Victoria. The net benefits to society over a 21 year period were estimated by determining the economic surplus accruing to participators each year and then subtracting all Government monies involved. The net social benefits, unlike the benefits reported for the New South Wales scheme, have on average been positive and have been consistently positive over the latter years of the data.

A redescription of Penaeus (Melicertus) Canaliculatus (Olivier, 1811), a wide-ranging Indo-West Pacific Shrimp (Crustacea, Decapoda, Penaeidae) Naturalis
Pérez Farfante, I..
In the original description of Palaemon canaliculatus, from "mer des Indes", Olivier (1811) presented the following observations among other more general ones: carapace with median sulcus extending from near posterior margin to base of rostrum, and two lateral ones beginning at same level as median sulcus and reaching tip of rostrum; ventral margin of rostrum bearing single tooth near apex, and lateral margins of telson setose and slightly spinous (un peu épineux). These features indicate that his species is closely related to, if not one of, the following Indo-West Pacific Penaeus: P. japonicus Bate, 1888, P. latisulcatus latisulcatus Kishinouye, 1900, P. latisulcatus hathor Burkenroad, 1959, P. longistylus Kubo, 1943, and P. plebejus Hess, 1865, the only...

A report on a small collection of shrimps from the Kenya National Marine Parks at Malindi, with notes on selected species Naturalis
Bruce, A.J..
The marine caridean fauna of East Africa has been little studied. Prior to World War 1, German authors produced a number of general studies but the emphasis of these papers was on crabs. Most of the carideans are reported from Zanzibar. Hilgendorf (1869) reported two unidentified species of Alpheus from Zanzibar. Pfeffer (1889) reported Coralliocaris graminea also from Zanzibar and in 1894 Ortmann added the hippolytid Saron marmoratus. Lenz (1905) reported three pontoniine shrimps, two hippolytids and six alpheids from Zanzibar. In 1905 also, Nobili reported Gelastocaris paronae from Zanzibar. The first World War terminated these studies and there seems to have been little further interest until Taramelli (1955) reported again on the crustacea of Zanzibar,...

A review of the hispaniolan colubrid snake Genus Ialtris Naturalis
Schwartz, Albert; Rossman, Douglas A..
Of the four endemic Hispaniolan genera of colubrid snakes, the least known is Ialtris Cope. Two species of Ialtris are recognized, each monotypic – dorsalis Günther and parishi Cochran. Neither has been commonly collected. COCHRAN (1941 : 375) listed 12 specimens of I. dorsalis in American collections and presented data from five specimens in the British Museum and the Hamburg Museum. parishi has been known only from the holotype. Our interest in Ialtris stems from a variety of sources. First, collections made by the senior author in Haiti and the República Dominicana since 1962 and latterly under the sponsorship of National Science Foundation grants GB-7977 and B-023603 have included a few specimens of Ialtris. In addition, collections at the Museum of...

A revision of Peliosanthes (Liliaceae) Naturalis
Jessop, J.P..
In the introduction a history is given of the development of the knowledge of the taxonomy of the genus Peliosanthes in the wide sense, including the generic names Teta, Bulbospermum, Lourya and Neolourya, in which altogether 35 specific epithets have been validly published, ranging from the Dcccan Peninsula through S. E. Asia to West Malesia. The characters defining these genera are scrutinized and it is found that only one genus can be distinguished. The affinity of Peliosanthes, which is maintained in Liliaceae, is discussed and it is concluded that it should be arranged in the same tribe as Ophiopogon and Liriope. A thorough examination is made of specific delimitation on the basis of the gross morphology which has shown that no satisfactory...
