' ‘‘A small shark resembling Mustelus himiulus and R. henlei, but differ- 
ing from the former in the dentition and in the attachment of the em- 
bryo to the uterus by a placenta, and from the latter in the blimtei 
teeth. Only those in the posterior part of the upper jaw have a basal 
cusp, and these nsnally but one only. This species is found on the 
coast of Europe and Africa, and is accredited to oiir Atlantic fauna by 
Giinther (viii, 38C).

Page 21: Galeorrhinus galeus, the “Oil Shark”, is very abundant on 
the coast of California, especially southward. Its teeth are coarsely 
serrated on the outer margin near the base only. Galeocerdo Ugrimis 
also ranges northward to San Diego on the Pacific coast. ,

“ Body rather robust, the head broad and depressed ; month inferior, 
with the teeth in both jaws strongly serrated in tlie adult; less so or 
entire in the young ; those in the upper jaw broad, those below narrow, 
straight, and nearly erect. No spiracles. First dorsal large, placed not 
far behind pectorals. Pectorals falcate. Second dorsal small. Em- 
bryos attached by placentm to the uterus as in ScoUodon and Bhinotna- 
cis.* (In Carcharimis placentm are not developed, according to Auguste 
Dumeril, Hist. Nat. des Poiss. i, 244.) Species numerous, {eo, well;
