most probably vittata of Peters. He sent a drawing of a middle-aged 

 specimen to Prof. Peters, who says that there is no distinction traceable 

 between the figure of the Kachh specimen and the type of vittata. The 

 head, above, is spotted with dark, and the entire carapace is marked with 

 very numerous irregularly radiating dark streaks. The granulation of the 

 carapace becomes apparent after the epidermis has dried up, in fresh specimens 

 no trace of it is to be seen. Young specimens are rather flat, but in old 

 ones the convexity of the carapace is very considerable, and the shell is 

 somewhat depressed along the centre. The species is common both in rivers 

 and tanks, and is often met with crawling from one pool of water to another ; 

 I have seen specimens up to a length of 15 inches. One, recently received, 

 has the carapace 105 inches long, and 7 '7 broad across the abdomen ; and 

 the total height is nearly 3 '5 inches. The odd osseous antero-central plate 

 of the sternum is broadly rounded, somewhat narrower in front than behind, 

 l - 3 inch long and 1*5 inch broad ; the two posterior plates form a suture, 

 2'3 inch long, they are perfectly united, as in F. Ceylonensis, which has a 

 quite similar coloration, and to which vittata is united by Gray in Shield

Notes on Fish, collected by De. Stoliczka in Kachh, — 



by Surgeon Major F. Day. 



[Received 26th June, read 3rd July, 1872.] 



I am indebted to Dr. Stoliczka for the following eighteen species of 

 fish with their local names, collected by him during his recent tour through 

 Kachh. They are interesting as extending our knowledge of the localities 

 to which species spread, and also as first demonstrating the existence of the 

 Genus Cyprinodon in the fresh waters of India. 



Fam. — GoBinxan. 



1. Gohius giuris, Ham. Buch. Kliarba Mali. Tulli, Kachh. 

 Five specimens up to 6 inches in length. 



The inferior pharyngeal bones are each of a triangular shape, the base 

 being external, whilst the two bones are closely approximated together 

 along nearly two-thirds of their internal margins.
