SEMISAGITTATED SHARK.

dentato denikulis semisagittatis. 

 Shark with flat sword-shaped snout denticulated on both sides 



with semisagittated teeth./ 

 Yahla. Russ. ind. t. Yd, 



I AM induced to consider this fish as a distinct 

 species, from the remarkable circumstance an- 

 nounced in the specific character. The length of 

 the specimen observed by Dr. Russel was about 

 thirty-four inches, of which the snout measured 

 something more than seven inches: the general 

 shape of the animal is similar to that of the preced- 

 ing species; the back and sides are convex, and 

 the belly flat : the mouth furnished with numerous 

 granular teeth : the number of spines or processes 

 on the snout is about twenty-six on each side : 

 every tooth or process being semisagittated, or 

 pretty deeply denticulated on one side, viz. that 

 towards the back of the fish. Native of the In- 

 dian seas. 



I may here observe that these long-snouted 

 Sharks seem considerably allied to the long-bodied 

 Rays, such as the R. Rhinobatos, &c. and may be 

 said in some degree to connect th^ two genera of 

 Squalus and Raja. ' ,
