JENYNSELLA gexi. no v. 
Body elongate and subfusiform, scaleless. Lateral line repre- 
sented by a series of small pores along the middle of the sides. 
Head small and subcorneal, its upper profile feebly convex ; snout 
short and rounded. Mouth terminal, with narrow, oblique cleft, the 
jaws equal. A single series of small, stout, conical teeth in each 
jaw ; vomer toothed ; palatines toothless. Nostrils large and open, 
contiguous. Eyes of moderate size, anteromedian, lateral. Kayed 
dorsal fin originating above the anus, with 9 rays, its posterior rays 
opposite to the anal fin ; adipose dorsal wholly behind the anal fin : 
anal fin with 14 rays : caudal deeply forked : pectoral small, 
rounded, symmetrical, inserted very low, almost on the ventral 
profile below the gill-opening, with 9 rays, the middle the longest: 
ventrals rounded, with 7 rays, inserted close together and much 
nearer to the tip of the snout than to the base of the caudal. Gill- 
openings wide ; gill membranes separate, free from the isthmus ; 
five branchiostegals ; pseudobranchia3 large ; gill-rakers in small

D. 9 ; A. 14 ; P. 9 ; V. 7. Yentral profile more arched than 
that of the dorsal ; width of body If in its depth, which is 5^- in its 
length. Head compressed, its length 4| in that of the body. Snout 
short and blunt, rounded above, its length f of the diameter of the 
eye, which is rather more than of the length of the head. Inter- 
* Johnston's brief description of Haplochiton sealii gives, as previously men- 
tioned, no clue as to the generic affinity of that species ; but on the supposition that 
the two Australian species are congeneric, I give the following synopsis by which 
they may be easily distinguished — 
a. Body very slender, its depth 10 in the total length ;f head depressed ; anal 
fin long, with 19 or 20 rays sealii 
aa. Body comparatively robust, its depth more than 7 in the total length ;f 
, head compressed ; anal fin shorter, with 14 rays ... ... weatherilli 
t From tip of snout to extremity of caudal fin.
