THE DISCOBOLI. 61 



median. As in the other species, this organ is much affected by individual 

 variation. The stomach closely resembles that of L. Montagui, but in the 

 examples dissected has only ten to thirteen cceca, whereas that species has 

 more than twenty. Each of a number of the cseca contained a small 

 lump of a dark-colored substance. The food in the stomach was composed 

 entirely of small Crustacea. The bladder is of moderate size ; the kidneys 

 are elongate, slender, more massive anteriorly, and confluent backward ; 

 and the intestine is as long as the distance from the vent to the tip of 

 the tail. 



In the earlier synonymy allowance must be made for the inclusion of two 

 or moi'e species, which may not be separated with any degree of confidence 

 by means of the data given by the authors responsible for the mixture. Thus 

 Cuvier evidently included L. Agassizii, from Bloch, with this species, and he 

 was followed by a number of others.

A rather stout species, in which the body cavity ends, and the anal fin 

 begins, at the middle of the length without the caudal. The length of 

 the head equals its width, and is contained three and two thirds times in 

 the length of the body to the base of the caudal. Above the bases of the 

 pectorals the dorsal outline is greatly arched ; the height is three elevenths 

 of the length, if the caudal is excluded. Below the sixth ray of the dorsal 

 is the first ray of the ventral ; from this point backward the body is much 

 compressed and tapers rapidly. Forehead flattened ; snout thick, blunt ; 

 mouth anterior, horizontal, not reaching a vertical from the front of the 

 eye. Anterior nostril tubular, near the eye ; posterior above the eye, 

 on the interorbital space. Eye small, equal to length of snout, half of 

 interorbital space, or little less than one fourth of head. Teeth numer- 

 ous, in alternating series, small, short, tricuspid, with broadly spreading 

 cusps. 



Dorsal and anal low anteriorly, widest near the middle of their lengths, 

 continuous with the caudal. The last not distinct from dorsal and anal.
