13. Tetrodon trichocephalus Cope. 



Described from the Powell collection ; not since recognized. 



14. Sanzania truncata (Retz). 



Given in Jordan and Gilbert's Synopsis Fish. N. A. as " occa- 

 sional off our Atlantic Coast." The specimen in question came 

 from the Bermudas. 



b. Species admitted through erroneous identifications. 



1. Galeus galeus (L.). 



Recorded from California by Dr. Giinther and later by Jordan 

 and Gilbert. Our specimens are since recognized as belonging to 

 a distinct species, G. zyopterus J. and G. 



2. Carcharias plumbeus Nard >. 



( Carcharias milberti Val. ) 

 One of the types of Carcharias milherti Yal. came from 

 Milbert's collection, " New York." The others were from the 

 Mediterranean and belongs to the previously described G. plum- 

 beus. Milbert's specimen was probably either C. coerideus.i or 

 else from some other locality. In any event, G. milberti Yal. 

 should not have a place in our lists. 



3. Carcharias lam'a Ri.=so. 



First ascribed to our fauna by Putnam, from a tooth found on 

 St. George's Banks ; afterwards by Jordan and Gilbert from 

 specimens taken at San Diego, California. The latter belong to 

 distinct species (G. lamiella J. and G.). The species, however, 

 occurs in abundance about the Florida Keys, and it should be 

 retained in our lists. 



4. Isurus glaucus Mttller and Henle. 



Our fish does not agree well with Miiller and Henle's account 

 of the East Indian glaucus. It is probably distinct and should 

 stand as I. dekayi Gill. 



5. Isarus spollanzani Raf. 



Certainly not yet positively known from our coast. De Kay's 

 Lamna punctata is Isurus dekayi. Storer's Lamna punctata is 

 Lamna cornubica. 



6. Heptranchias indicus (Cuvicr). 



The Californian species, H. maculatus Ayres, has been erro- 

 neously confounded with this East Indian shark.
