The British Museum possesses various specimens from Australia, which may be divided 

 into two groups ; one having a more slender beak and the barbels placed midway between 

 the base and tip, and the other having a wider beak, with the barbels nearer the base. There 

 is a Japanese specimen also in the museum.

 Pteroplatea japonica, Temm. et Schl. F. J. Sieb. 



The British Museum possesses two foetal specimens from Japan which measure 5| inches 

 across the disc, 3 along it, and 4f including the tail. They seem to differ very little from 

 Pteroplatea micrura. 



Hab. Sea of Japan. 



Tetrodon pcecilinotus, Temm. et Schl. F.J. Sieb. Rad. D. 13 ; A. 11 ; 



C. 8£; P. 15. (Spec. Brit. Mus. 8 inches long.) 



This Tetrodon is marked much like T. albo-plumbeus, but the spines extend further along 

 the back to the tail, and there are some slight differences in the courses of the porous lines. It 

 is probable nevertheless that it is the same species with albo-plumbeus, since there are two other 

 Japanese specimens in the British Museum, which are intermediate between the two in the 

 extent of the spiny surface and in other minute characters. This being the case renders it 

 probable that the small specimen which we have reckoned to be a variety of ocellatus, under 

 the name of var. guttulata, ought also to be referred to albo-plumbeus. 



Hab. Sea of Japan. 



Tetrodon rubripes, Temm. et Schl. F. J. Sieb. Bad. D. 16; A. 13; 

 C. 9{; P. 17. (Spec. Brit. Mus. from Japan, 19 inches long.) 



Hab. Sea of Japan. 



(Tetrodon laterna), Tetrodon pardalis, Temm. et Schl. F. J. Sieb. 

 (Spec. Brit. Mus. 13 inches long. Rad. D. 11 ; A. 11 ; C. 9 ; P. 17. 



The specimen shows more spots than are exhibited in Mr. Reeves's drawing, and the nasal 

 cirrhus is scarcely so much developed, but there is no reason to doubt the identity of laterna 

 and pardalis. The skin is smooth throughout, but pits slightly on the belly in drying.
