its length. The greatest depth, which is at the occiput, is slightly less than the great- 
est breadth. The vent is half-way between the snout and the root of the tail. 
The first dorsal ray arises at the level of the upper end of the gill-openings. The 
first six rays are short, delicate and flexible but not articulate. The 
posterior sixteen rays are longer, stouter and articulate. The dorsal 
and anal fins are separated from the caudal by an interval which is 
equal to a quarter of the length of the head. The twenty- three 
pectoral rays are attached along a line opposite the lower half of the 
gill-openings. The uppermost and longest rays are equal to the post- 
orbital part of the head. The pelvic rays are about half that length. 
The caudal fin is about one-fifth of the total. One specimen measur- 
ing 55 mm. from 643 fathoms in the Bay of Bengal, Station 372. In 
the fresh state the fish seems to be blind, both orbits being covered by 
opaque skin, but on the right side the eye-ball could be seen through 
the skin, though not on the left. On dissection it was found that the 
right orbit contained a well-developed eye but that the left contained 
a small rudiment. The specimen did not appear to be damaged in any 
way.

The pectoral and pelvic fins of this specimen so closely resembled those of Parali- 
paris latifrons as figured by Garman {Memoirs Mus. Comp. Zool. 
Harvard, xxvi, pis. xxvii and xxviii), that it was first thought that 
the pelvic fins must be merely the lowest detached rays of the 
pectoral arch as in that species, and not true pelvic fins. Dissection, 
^ Limb however, showed that well-developed pelvic bones were present, the 
girdles of L. heati- anterior ends of which were in contact with the lower ends of the 
champt. pectoral arch, and the four pelvic filaments were clearly attached to

tached rays of Paraliparis were originally pelvic rays which acquired a secondary 
attachment to the pectoral arch during the reduction of the pelvis to its rudimentary 
condition.

The length of the preorbital process is equal to one-third of the distance between 
its extremity and the anterior border of the orbit The preocular ridge has a 
prominent, finely serrated border ; it ends behind in a sharp spine, which is nearly as 
long as the eye. The inner borders of the preorbital processes are parallel, their outer
