The description given by Linuajus of Balistes Mspidus is based on a 

 specimen, evidently of the i)resent species, received by him from Sonth 

 Carolina through Dr. Garden. The body was " hispid, roughened to- 

 wards the tail with sette." A reference is also made by Linnaius to 

 the account given by Seba of Monacantlms longirostris. This, however, 

 cannot invalidate a description made from a specimen in hand, and the 

 name his2}idus must be used for our species. 



123. Ostracium quadricorne Ijhin.—Cow-Jiah. 

 Very common. 



124. Lagocephalus lasvigatus (Linu.) Gill. 

 Two specimens seen. 



125. Tetrodon turgidus Mitcli. 

 Common. 



From specimens of T. nephelus in our collection from Pensacola and 

 Galveston, this species differs conspicuously in its coloration, in having 

 the snout entirely covered with spines, and in having all the spines short 

 and immovable. T. nephehts has a broad space below eye, and the snout, 

 with exception of a small median patch above, naked, and the spines of 

 head and body are longer, slender, and erectile. 



126. Cliilomyctertis geometricus (Bl. & Schu.) GiW.—rin-cushion. 

 Very abundant. 



Very young specimens have the body soft and flabby, with the spines 

 admitting of considerable movement because of the looseness of the 

 skin ; the caudal peduncle is scarcely noticeable ; the belly is often of 

 purplish black, with pink spines.
