Pristis annandalei , sp. nov. 



Length of the rostrum in the total length 4*8 ^ height of 

 body 10" 84^ greatest breadth 6 in the total length. Breadth of 

 rostrum at tip in the breadth of rostrum at base 175. The ros- 

 trum is armed with about 25 pairs of teeth ^ the left side having 

 one more tooth than the right. The two anterior pairs and the 

 two posterior ones are opposite to one another, the rest of the 

 pairs do not lie opposite. Interspaces between teeth vary greatly, 

 the diameter of the sockets of the teeth being contained in the in- 

 terspaces differently, from 4 to i : teeth are mostly unequal and 

 uneven. Mouth transverse, with a membranous valve or fold 

 hanging from the upper edge of the upper jaw behind the teeth,

with two round lobes at two ends. Spiracles large and oblique, 

 posterior to the eyes, the diameter of the eye being contained 4-6 

 times in the distance between the eye and the spiracle which is 2-1 

 diameters of the eye in length. Fins : first dorsal is neither en- 

 tirely behind the ventral nor opposite to it, but commences 

 slightly posterior to the anterior side of the ventral fin ; second 

 dorsal smaller than the first, not reaching the caudal ; the distance 

 between the second dorsal and the caudal contained 275 times in 

 the distance between the two dorsals. The caudal has a distinct 

 lower lobe, which is decidedly round. The keel is very imperfectly 

 developed on the posterior part of the tail. Pectorals triangular, 

 the distal angle almost a right angle.
