The width of the mouth when fresh was 3 feet ; but it has 
shrunk in drying to 1 ft. 1lin. The form of the mouth is lost 
in the mounted specimen. When fresh the lower jaw was 
quite straight and flat, nearly, if not quite, on a level with the 
surface of the abdomen, and considerably in advance of the 
upper, so that the band of teeth in the lower jaw was quite 
uncovered. This band averages 1 inch in breadth, and con- 
sists of fourteen rows of minute, sharp, recurved teeth, 2 millim. 
long, all of equal size. The band in the upper jaw is ? inch 
broad, and consists of eleven rows of similar teeth. I was 
in hopes of finding either eggs or embryos, which are occa- 
sionally to be obtained from large sharks and skates caught 
at this season ; but there was no sign of her having approached 
the shore on account of its being the breeding-season. The 
stomach contained a quantity of finely divided red matter. 
This makes the sixth species, obtained mostly near Colombo,’ 
not mentioned in Day’s ‘ Fishes of British India,’ and now in 
the collection of the Colombo Museum. They are :— 
Branchiostoma lanceolatum, Pall. 
Rhinodon typicus, Smith. 
Diodon maculatus, Giinth. 
Chilinus undulatus, Riipp. 
Xiphochilus robustus, Giinth. 
Peristethus ? Near Galle, deep water, probably 
about 50 fathoms.
