This genus must now be known by the above name, as Dr. Gill's 

 specification of Catulus stellaris Smith as the type of Catulus^ is not 

 admissible. Under Catulus three species are included by Smith, viz.: 

 Squalus canicula Linn., Scyl. marmoratum Bennett, and C. edwardii 

 Smith. The first of these is here considered as the type, thus allowing 

 it to fall a synonym of Scyliorhinus Blainville. The type of Poro- 

 derma Smith may be considered its first species, Squalus africanum 

 Gmelin. 

 Galeus melastomus Rafinesque. 



Head 6yV to 7; depth 10 to 14|; snout 2 to 2f in head ; eye 3f to 4f ; 

 width of mouth ly^o to 2f ; interorbital space 2 to 2f ; first dorsal If to 

 2|; second dorsal If to 2f ; base of anal 1 to If; caudal from origin of 

 lower lobe 2^ to 3f in rest of body; length 7 to 18|- inches. Ten 

 examples. Italy (Bonaparte, No. 253). 



Also 3 dried skins without data. 



The above generic name may be adopted for this genus, as Rafinesque 

 includes but two species. They are G. melastomus and Squalus uyato, 

 of which the first may be considered the type. If his intention was to 

 have made S. galeus Linnaeus his type he certainly has missed the 

 opportunity, as that species is not even mentioned, and the inference 

 may be only surmised by reference to his Ind. It. Sicil., 1810. 

 Pristiurus Bonaparte is thus superseded by Galeus Rafinesque. 



HEMISOYLLIID^. 

 Chilosoyllium indicum (Gmelin). 



Three examples from Padang (C. H. Harrison, Jr., and H. M. HiUer), 

 Sumatra. Color when fresh in arrack more or less uniform dull brown, 

 lower surface of head, abdomen, and bases of pectorals and ventrals 

 dirty cream-white. The largest 21 inches long. The youngest with 

 very distinct markings. One specimen now in Stanford University. 

 Oreotolobus japonicus (Regan). 



One example without data. The Japanese material called 0. 

 harbatus by Jordan and Fowler^ is this species. 



GINGLYMOSTOMID^. 

 Ginglymostoma cirratum (Gmelin). 



One from St. Martin's (R. E. Van Rijgersma), W. I. Three other- 

 dried skins, and one alcoholic, may have the same data. They are all
