240 WAITE 
leneth is 1.3 in the head; the eight upper rays are divided, the 
lower ones are simple; these latter rapidly decrease in length, 
forming a lower concave margin; the ventrals are very short, not 
reaching the vent by an eye diameter, and are contained thrice in 
the length of the head; the caudal is truncated and the depth of 
its peduncle equals the interorbital space. 
Scales.—The head is entirely naked as is also the space behind 
the pectorals and between the ventrals; the scales are small and 
deeply imbedded on the occiput, but they become larger, and 
imbricate, those on the tail being largest. The lateral line arises 
above the opercle and gradually descends to the mid line, thence 
running straight to the caudal: its scales are very large and 
leaf-shaped with a central ridge, the line is therefore extremely 
conspicuous. 
Colours.—Except quite anteriorly the lateral line sharply 
divides the colouration, that above being brown, each scale with 
a darker dot, the upper part of the head is brown dotted, the 
entire lower parts are white: a row of about five brown spots 
is found on the front of each ray of the dorsal, but the other fins 
are without markings. 
Length.—378 mm. 
The only specimen obtained was taken off Otago Heads, in 
55-102 fathoms. While L. robsoni Hector,4® and L. canis 
Arthur,47 are without doubt synonyms of L. angusticeps, and 
with which my specimen quite agrees, this latter species does 
not conform to either Giinther’s description or figure, which, 
however, are not in themselves entirely consistent: thus the body 
is illustrated as far deeper than described. In my specimen the 
ventrals do not reach the anal by fully half their length, and 
the shortness of these fins is indicated by Hutton’s figure. 
Giinther describes the ventrals as extending to the fourth anal 
ray: he also describes and figures the interorbital space as much 
narrower than found by Hutton and myself. The transverse 
rows of scales are rendered as 7/7, but they are much more 
numerous in my specimen, counted from the origin of the dorsal 
fin. It is possible that there are two allied species in our waters, 
but for the present I follow authors in regarding the genus as 
monotypic, indicating the essential features of the Otago 
specimen as above.
