166 ~ 
females. This was confirmed by dissecting a large number 
of specimens, when it was seen that the ovaries were fairly well 
developed, and it was probably the spawning time. 
Ipnops Murrayr, Gunth. 
One specimen of this interesting fish was procured by shrimp 
trawl off Cape Point (N.E. by E. 3 E., 40 miles), from a depth 
of 800-goo fathoms ; Reference No. 16,897. It differs from 
the description of the type in having anal slightly further for- 
ward, the pectorals somewhat longer (extending to middle of 
ventrals). There is also a small patch of teeth on each of the 
palatine bones. 
Total length, 54 inches. 
The Challenger specimens were obtained off the coast of 
Brazil (1,600 fathoms), near Tristran da Cunha (1,900 fathoms) 
and north of Celebes (2,150 fathoms). 
Bathypterois filiferus, n.sp. 
(Plate XLVIT)) 
Depth of body nearly 6 times in length (223 mm.) without 
caudal, head 4} times. Interorbital space 2.3 in length of 
head, wider than length of snout which is 2.6 times. 
Teeth in jaws and vomer. 
Anus about midway between pectoral and anal, and has a 
small papilla. 
The upper pectoral ray is very long (405 mm.), nearly twice 
the length of the body, reaching far beyond the tip of the 
caudal. It is not bifid, but the second ray is closely applied to 
it so as to make them appear as one. They separate at a point 
opposite the adipose dorsal fin. The free portion of the second 
is about half the length of the head and is bifid. The third ray 
is small, being about 44 in the depth of the body ; the fourth 
ray is half the size of the third, and is separated from the other 
rays of the pectoral by a space about equal toitslength. Of the 
12 remaining rays, the longest reaches to the posterior end of 
the base of the caudal fin. 
The two external rays of the ventral are short and bound 
together for about ? of their length. They are dilated at their 
extremities, which reach nearly to the root of the caudal. 
The dorsal fin commences at the middle of the body, and the 
anal commences below the end of the dorsal.
