A Notoc.aiitlins with elongate body, whose greatest height lies between 

 the pectoral and ventral fins and is contained about four and one half 

 times in the distance from the vent to the tip of the snout. Head short, 

 compressed, its length not quite three and one-half times in the distance 

 from vent to snout. Mouth large, extending backward to a point nearly 

 under the eye; the maxillary nearly to the vertical from the anterior 

 margin of the pupil. The mouth does not lie entirely on the under 

 portion of the head, but is sublateral. There are thirty-five teeth 

 in the intermaxillaries on each side. The distance between the upper 

 profile of the head and the eye is about equal to the diameter of the 

 eye, which is slightly greater than one-third the length of the snout 

 (certainly not more than one-half the length of the snout) and about 

 one-eighth the length of the head. [In this connection it is taken for 

 granted that the hole in the skin of the head represents the size of the 

 eye. If, however, we assume that tlie entire portion free of scales is 

 the eye, the diameter is greater and equal to one-sixth the length of the 

 head. It is, at any rate, considerably less than the width of the inter- 

 orbital space.] The gill-cover appears to be divided to below the sym- 

 physis of the operculum (with hyomandibular), and is free from the 

 isthmus. 



Scales are lacking only about the mouth and eyes; about forty rows 

 of small scales (2 mm. broad, 4 nun. long) between the ventral outline 

 and the lateral line: smooth and imbricated. 



Of the eleven dorsal spines, the first (overlooked by Bloch and Val- 

 enciennes) is very small and only visible as a point; placed close to 

 this (1mm.) is the second, which is also very short and feeble. Tlie 

 third, though also short, is thicker. The vent lies behind the fiftli 

 spine. Of the fifteen aiml spines, which have their origin immediately 

 behind the vent, the first (overlooked by Bloch and Valenciennes) is 

 very small; it does not extend beyond the profile; the second and third 

 but slightly. The spines which are longest and placed farthest bade 

 still bear traces of a connecting membrane, and are probably only worn- 

 oft'rays. The pectorals are inserted somewhat farther back from the 

 gill-covers than shown by Bloch ; the end is surely broken off, but yet 

 it can hardly be doubted that this fin is too long in Bloch's figure; its 

 base is less than one sixth the length of the head. The ventral fins, 

 connected together behind the median line by a membrane, terminate 

 considerably in advance of the vent (they are apparently worn off a 

 little behind).
