Hahitai. — Both coasts of Tropical America ; var. testudineus, from Vir- 

 ginia to Baliia ; var. annulatus from Gulf of California to Galapagos 

 Islands. 



This species is common through the West Indies and it ranges occa- 

 sionally northward, as far as the coast of Virginia. Ou the Pacific 

 coast it seems to be equally common. 



We have seen from either coast only young examples of this species 

 (2 to 6 inches long) and all of these have the spines on the back and 

 belly well dev^eloped. The adult form, as elsewhere stated, is probably 

 the species called ^pha^roides poUtus. 



We have been unable to distinguish Atlantic specimens (testudineus) 

 from Pacific specimens {anmtlatus), but in deference to the opinion of 

 Dr. Giinther, we have separated the synonymy into two series, and we 

 have also indicated in the key the supposed differences of the two forms. 



The extensive synonymy of this species needs no special remark. The 

 name testudineus is the earliest given binomially by Linnseus to any 

 Tetrodont, and its application to the present species has been unques- 

 tioned since the error of Bloch and his copyists was corrected by Giin- 

 ther. Both Linnajus and Balk correctly describe the dark spots and 

 the pale curved lines or "sutures" on the back. 



10. Sphaeroides formosus. 



Tetrodon formosus Giinther, Cat. Fish. Brit. Mus., viii, 183, 1870 ("South 

 America'"). 



Ilabitat. — (" South America.") 



This species is known to us only from the description of Dr. Giiu-
