opening is equal to the difference between the trunk and tail, 

 viz. : 78 mm. The mouth, deeplj cleft, is to the head as 8 to 

 17 ; the eye being o ver the middle of the upper jaw, and its 

 diameter is one-sixth of its length. The posterior nostril is 

 in front of the eye ; the anterior one is tubular, and at the 

 tip of the snout. The mouth is bordered by three pores above 

 and below. 



The teeth of the nasal plates are long, vertical, sharp, three 

 in number on the middle line, and six on the outside, not so 

 long, with shorter ones between these last ; the vomerines are 

 short, and on one row. The palatines are small, excepting a few 

 longer ones in front. On the lower jaw they are small, re- 

 curved, with two longer ones on each side in front. 



The body is marbled with brown on a greenish ground, which 

 is dark enough to almost obscure the marblings, which are com- 

 posed of close-set spots, as large as the pupil of the eye, often 

 bordered on one side with a white edging ; the spot sometimes 

 being all white, especially on the front of the body. The indi- 

 viduáis of the same age of allied species do not show this color- 

 ing. The abdomen and throat are paler, without marblings, 

 but with some spots of a dirty white. The head has, on each 

 side near the head, six lines or longitudinal folds, the longest 

 prolonged under the lower jaw. On the dorsal, which begins 

 near the middle of the head, there are some oblique folds. The 

 rays of the fins are very slight and very numerous. The dorsal 

 has a blackish border, sometimes interrupted by white ; its 

 height, over the anus, is one-quarter that of the body, and in- 

 creases gradually on the tail. The anal is one-third the height 

 of the dorsal : all black, with a white border. The iris is yel- 

 low. It bears No. 736 in my Atlas. 



Peristedion micronemiis, Poey. 



It is the same as the one described by me as the P. imberbe, 

 in the Memorias, II., p. 367; Eepert. II., pp. 158, 304, 462. 

 With the lens, a very small tentacle is seen near the angle of
