Family CHIASMODONTIDÆ:. 
Genus Kali, nov 
A genus allied to Chiasmodus (Johnson), differing from it in the reduction of the 
operculum, in the character of the teeth, the presence of a double row of pores in the 
lateral line, and in possessing pyloric cæca. 
The body is scaleless and covered with thin, loose, black skin. There are two 
separate dorsal fins, the anterior slightly shorter than the pösterior which is equal 
and opposite to the anal. The ventrals are thoracic but slightly behind the level of the 
pectorals. The mouth is very wide. The opercular bones are much reduced so that 
the angle of the lower jaw forms the posterior limit of the head. The teeth are few 
and very large, with arrow-headed points ; they are arranged in two series, those of 
the inner series being much the larger. The vomer is toothless ; the palatine bears a 
few large teeth. Upper pharyngeal teeth are present. All the teeth are depressible 
inwards. The gill-aperture is very wide. There are four long slender gills with very 
short filaments. There are no pseudobranchiæ. The stomach is cæcal and very large. 
There are two pyloric cæca. Air-bladder present.

The head is a quarter of the total length without the caudal. The greatest depth, 
which is just in front of the attachment of the pectorals, is a fifth of the total. The 
length of the snout is equal to the interorbital breadth and half as long again as the 
diameter of the eye, which is a fifth of the length of the head. The mouth is. very 
large and extends far behind the eye. The upper and lower jaws meet only at their 
articulations and in front ; they curve upwards and downwards in the middle of their 
length. Because of this curve the teeth can stand erect. When the mouth is closed, 
the upper and lower jaws are separated in the middle of their length by a distance 
greater than the diameter of the eye. There is a deep bony depression on the top of 
the head limited by two ridges which converge and meet in the middle of the upper 
surface of the snout. On either side of these ridges are two deep depressions in the 
bone (the loose skin has become detached from the head in the single specimen). The 
openings of the gill-cavities are very large. The gill-coverings are completed below 
by a thin membrane which is so voluminous that in the dead specimen it is not ren- 
dered tense until the angles of the jaw have been separated laterally from one another 
by a distance equal to the length of the head. The gill-arches are very long and slen- 
der and are freely exposed. Their filaments are short, being equal to half the dia- 
meter of the eye. The teeth are alike in both jaws ; they consist of an outer series 
of ten teeth increasing in size from behind forward — the largest being slightly less in
