1. Talorchestia brito Stebbing. In examining a lot of Orchestia gammarellus (Pallas) (= O. littorea (Montagu)) collected many years ago at Katwijk by Dr. J. A. Herklots, late conservator of Invertebrates at the Leiden Museum, I came across some fine specimens of Talorchestia brito Stebbing, which have evidently been picked up together with the common Orchestiae. The sample was undated, but as Dr. Herklots died in 1872, the specimens must have been caught on our sea-shore long before Stebbing described his new species, in October 1891 (Ann. Mag. Nat. Hist., ser. 6 v. VIII p. 324—328, pl. XV), obtained plentifully in the summer of this year „on Woolacombe and Saunton Sands, in North Devon". Afterwards Chevreux found it, likewise in abundance, on the shore of Verdon (Gironde) in August 1893 (Rev. biol. d. Nord d. 1. France, t. VII, 1894—95, p. 158), but no further record seems to have been given since that time. Though Stebbing characterized his species with his usual accuracy and gave some figures of the gnathopods, the last joints of the pereiopods and the telson, I have thought it not superfluous to give a full account of the characters of my specimens, which were all males (12 in all). I have not been able to recognize the females of this species, which in my opinion are scarcely, if at all, to be distinguished from Talitrus saltator (Montagu) (= T. locusta (Pallas)), as I shall explain further on. With regard to the distinctive characters of Talorchestia, it has been rightly remarked by Stebbing, that this genus is composed of the genera Orchestia and Talitrus, indeed in such a manner, that the males of Talorchestia should be referred to Orchestia, while the females are
