terior angle of the pectorals; its height is less than the depth of 

 the body, and the posterior lobe is greatly produced. Second 

 dorsal similar to the first, (hough smaller, the hinder end of its 

 base placed over the middle of the anal, and a little nearer the 

 origin of the ventrals thao the tip of the tail. Anal smallest, 

 similar to the second dorsal, and nearer the caudal than the 

 ventrals. Pectorals a little larger than the first dorsal, their 

 hinder margins emarginate. Ventrals small, their origins much 

 nearer that of the anal than of the pectorals. 



Total length, 895 mm. 



Obs. — The above description was drawn up from a fine female 

 example presented to the Trustees by Mr. J. Blair, who caught 

 it near Manly, Port Jackson. The only figure of the adult 

 published being very inaccurate, and the several descriptions either 

 too short or unsatisfactory, I take this opportunity of supple- 

 menting them.

Cheilobranchus parvulus, sp. nov. 



(Fig. 18.) 



Head nearly one-ninth of the total length, or 18 in the 

 distance between the gill opening and the vent, and equal to the 

 height of the body. The distance between the end of the snout 

 and the vent is 1 -7 to 21 in the remaining portion. Eye large, 

 one-fourth the length of the head, and covered by a transparent 

 membrane. Snout longer than the eye, the maxillary not quite 

 reaching its anterior margin. Nostrils placed on the upper 

 surface of the head, the anterior tubular, and placed just before 

 the eye, the posterior simple, and anterior to the middle of the 

 eye.

The dorsal tin originates a little behind the vertical of the 

 vent, and is highest above the commencement of the last quarter 

 of the fish. The anal arises behind the middle of the length, 

 and is similar in form to the dorsal. Both are united to the 

 caudal, which is distinguished by the presence of a few minute 

 rays, no traces of which are present in the other fins.
