propriety of the terms Beaumaris Shark and Monensis, by 

 which this fish is known. Some particulars of both exam- 

 ples are here added from Pennant. 



" The first specimen obtained was seven feet long ; the 

 snout and body of a cylindrical form ; the greatest circumfer- 

 ence four feet eight inches ; the nose blunt ; the nostrils 

 small ; the mouth armed with three rows of slender teeth, 

 flatted on each side, very sharp, and furnished at the base 

 with two sharp processes ; the teeth are fixed to the jaws by 

 certain muscles, and are liable to be raised or depressed at 

 pleasure. The first dorsal fin was two feet eight inches dis- 

 tant from the snout, of a triangular form ; the second very 

 small, and placed near the tail ; the pectoral fins strong and 

 large ; the ventral and anal small ; the space between the 

 second dorsal fin and the tail much depressed, the sides 

 forming an acute angle ; above and below was a transverse 

 fossule or dent. The tail was in the form of a crescent, but 

 the horns of unequal length ; the upper, one foot ten inches; 

 the lower, one foot one inch. The whole fish was of a lead 

 colour. The skin comparatively smooth, being far less rough 

 than that of the lesser species of this genus." 



" The second example was nine feet six inches in length, 

 that is, two feet and a half longer than the first, but each 

 part of this bore an exact proportion to the corresponding 

 parts of the other ; except that the nose of this, although 

 above one-third a larger animal than the former, was smaller 

 in every respect, being more abruptly tapering, but blunt 

 and shorter, as it measured but four inches and eight-tenths 

 from the eye to the end, whereas the snout of the smaller fish 

 was six inches in length from the end to the eye. This was a 

 vast animal ; its general circumference seemed greater in pro- 

 portion to its length, than that of the former, but it was par- 

 ticularly so at the region of the abdomen. This is readily
