Carcharias falcipinnis, Proc. Zool. Soc. 1839, p. 90 ; Trans, iii. p. 18. 

 This j)roves, as it was suspected, to be the Squalus ustus, Dum. ; 

 that is, Carcharias (Prionodon) melanopterus (Q. et G.) of MM. Miil- 

 ler and Henle. 



Carcharias microps, Proc. Zool. Soc. 1840, p. 38 ; Trans, iii. p. 18. 



This again may perhaps be found to be identical with the imper- 

 fectly known Squalus obscurus, Lesueur {Carcharias {Prionodon) ob- 

 scurus, Miill. et Henle), concerning which, however, the information 

 hitherto afforded is too scanty to allow the immediate adoption of 

 the name. Carcharias microps differs from C. P. Sorrah, Vol., as 

 described and figured by MM. Midler and Henle, in the equiserrate 

 teeth, the longer and narrower pectoral fins, the smaller eyes and 

 shorter muzzle. It differs again from C. P. Henlei (Val.), Miill. et 

 Henle, in the long and black- tipped pectoral fins,

Centrophorus calceus. — " Sapata."

Although I have not yet succeeded in obtaining the male of this 

 Shark, I perfectly concur in MM. Miiller and Henle's suggestion 

 (Plag. 2*^'" Nachtr. p. 199), that it will probably prove to belong to 

 their genus Centrophorus, with which I was unacquainted at the time 

 of its former publication. It is however quite distinct from either of 

 the species they describe. 



The other little shark, Acanthidium pusillum, nob., with which at 

 that time, in expectation of MM. Miiller and Henle's work, I pre- 

 ferred associating it, though not without considerable scruple, to 

 forming a new genus for a single species, is I think distinct specifi- 

 cally from Spinax niger (Buon.) of these authors {Sq. Spinaoc, L., 

 Acanthidium Spinax, nob.), with which they* have supposed it iden- 

 tical. It must retain also the name which I have given it ; that of 

 Spinax, which MM. Miiller and Henle, after the Prince of Canino, 

 have assigned to the same combination of characters, belonging, by 

 the right of priority f, to the distinct generic group to which these 

 authors have assigned the name already otherwise or in a wider 

 sense employed by Risso, of Acanthias, and the type of which is the 

 Squalus Acanthias, L.
