The tooth morphology of all the genera and subgenera of the Scyliorhinidae, with the unique exception of Pentanchus (not available for examination), is described and illustrated. Several systematic considerations are given. The odontology of the genera Centroscyllium and Aculeola, which are rather aberrant among the Squaliforms, is compared with that of all the Scyliorhinidae taxa presently described.

The teeth of nearly all supraspecific taxa of squaliformes are described and illustrated by SEM photos. The tooth morphology allows a direct assignment to all these taxa and some proposals of taxonomic adjustments. The results support opinions of other authors, that Echinorhinidae represent a separate order, Oxynotidae coincide odontologically with Squalidae; Squalid genera could be grouped into 8 subfamilies, 4 of which could not be defined hitherto; Centroselachus Garman, 1913 is confirmed and should be revalidated; significant odontological differences do not exist between Cirrhigaleus and Squalus, Lepidorhinus and Centrophorus, Scymnodon and Scymnodalatias,...

The tooth morphology of representatives of eight genera (incl. supraspecific taxa of uncertain status and validity) of the family Dasyatidae, two of Gymnuridae and one of Hexatrygonidae is described and illustrated by SEM-photographs. A differential diagnosis for a final conclusions on myliobatoid odontology will be given in a forthcoming issue dealing with the last myliobatoid taxa.

The description of micro-teeth within the Carcharhiniformes is hereby completed by presentation of generic representatives for the remaining families Proscylliidae, Hemigaleidae, Pseudotriakidae, Leptochariidae and Carcharhinidae. Detailed descriptions of the tooth morphology are given, as well as SEM-photographs. The tooth morphology of the genera herein concerned is compared with those published of the other carcharhiniform families in two previous issues of this series, in order to elucidate the interrelationships within this shark order also from an odontological point of view. The dental histology for the carcharhiniform genera is commented on, and their dental vascular types are re-examined. The results are summarized in a differential diagnosis for...

The morphology of the microteeth of the following taxa is described and illustrated with SEM-photographs in order to elucidate the interrelationships within the shark orders and families concerned and also from odontological point of view. Contribution 1b: The monotypic single genus of the hexanchiform Chlamydoselachidae. The tooth morphology of C. anguineus is compared with that of taxa of the only other hexanchiformes. The dental histology is commented on, and the dental vascular type is re-examined in order to understand the root form. The results are summarized in an odontological diagnosis for the genus. Investigational results on dental morphology, histology and vascularization recommend a reconsideration of the systematic position...

Part B, Nos. 1a and 1b of this series, comprising of the Batomorphii the first and the second sections on the Rajoidei, is continued with the last group of rajoid taxa as far as material was available. The tooth morphology of representatives of eleven more genera and subgenera, namely Arhynchobatis, Bathyraja richardsoni-type, Cruriraja, Irolita, Notoraja, Pavoraja (Insentiraja), Pavoraja (Pavoraja), Pseudoraja, Raja (Atlantoraja), Raja (Okamejei) and Rhinoraja, is described and illustrated by SEM-photographs. Differential diagnoses and systematic interpretations are presented as a result of the odontological examinations described here and in the previous two issues 1a and 1b for the supraspefic taxa of the Rajoidei.

The tooth morphology of all hexanchid species, including the controversial species Hexanchus nakamurai and H. vitulus, is re-examined and illustrated. Odontologically Hexanchus nakamurai is clearly distinct from H. vitulus. An odontological determination key to all hexanchid species is given. The odontological results presented suggest another intrafamilial ordering of the taxa than by the number of branchial arches, which seem to be less important.

Part B of this series, comprising the Batomorphii, is initiated with taxa of the Rajoidei. The tooth morphology of representatives of nine genera and subgenera is described and illustrated by SEM-photographs. An adapted terminology is introduced for the description of rajoid teeth, because their tooth morphology differs markedly in various aspects from that in selachians. A differential diagnosis for and conclusions on rajoid odontology, as well as an odontological key will be given in a forthcoming issue dealing with the last rajoid taxa.
