Dr. Giinther records a single specimen from the Bermudas. Another, 

 in the University Museum at Middletown, Connecticut, is said to have 

 come from the same locality. 



Additional data are necessary in order to determine the true relations 

 of Linne's Diodon atringa (atinga). Barneville and Bleeker consider it 

 identical with Diodon orbicularis of Bloch. Giinther does not commit 

 himself decidedly, although he cites, under Chilomycterus geometricus, 

 Marcgrave's Guamajacu atinga, upon which the species of Linne is pre- 

 sumably founded. The relations of the species D. atinga are important 

 as throwing light upon the relations of the genus Diodon, of which it 

 must be considered the type; there can be little doubt, however, that 

 Bleeker is right is retaining in this genus those forms which have three 

 rather than two roots to their spines.

A single specimen of two inches was found on the beach at Bayleys 

 Bay. The species ranges from Madeira and jSTorth western Africa to the 

 Caribbean, and no doubt frequently occurs about the Bermudas. Bloch, 

 in his description, figures the species with the imperforate nasal tenta- 

 cles of the genus Arothron, giving the East Indies as its habitat. Mak- 

 ing due allowances for the notorious carelessness of early ichthyologists 

 in fixing the localities of specimens, and for the lack of detail in their 

 drawings, we believe that the present name should be retained, since the 

 fish figured by Bloch is unmistakably the one before us. Should time 

 render it necessary to adopt another name, that of Banzani, who 

 described the species accurately, may be substituted.*
