M ACRURUS FABRIC II. 
Fig. 140. 
Snout pointed and deep , pyramidal , with the sharp sides continued after a break by the carince of the cheeks 
until they join the angle of the preoperculum: length of the snout greater than the least breadth of the inter- 
orbital space , ivhich is less than 1 / i (20*8 — 17*4 % in the specimens examined by us, which are between about 
72 and 78 cm. long) of the length of the head , than 3 /- (59*6 — 49*1 %) of the longitudinal diameter of the orbits , 
than ®/ 5 (54 — 42 %) of the post-orbital length of the head , than 1 / 8 (17*2 — 15*2 %) of the distance between the 
first dorsal fin and the tip of the snout, than 7- (54 %) of the breadth across the cheeks at the centre of the 
eyes , or than V 2 (47*2 — 37*6 %) of the length of the lower jaw , which is more than */ 5 (44*1 — 46*4 %) of the 
length of the head , than 1 / 3 (36*3 — 40*5 %) of the distance between the first dorsal fin and the tip of the snout, 
and greater than the postorbital length of the head. Mouth set on the under surface of the snout, but its breadth 
at the corners more than 2 / 3 (81 — 85 %) of the breadth across the cheeks at the centre of the eyes. Length of 
the head about 23 — 22 % (or less") of that of the body, 90 — 86 % of the distance of the first dorsal fin from 
the tip of the snout, about 2 / 3 (61 — 64*3 %) of that distance of the second dorsal fin, and rather more than 1 / g 
(56 — 52 %) of the distance between the anal fin and the tip of the snout. Depth of the body at the beginning 
of the first dorsal fin about V 5 — 7 g °f the length of the body, at the beginning of the anal fin about 1 / 1 of the 
same. Base of the pectoral fins only slightly brachiate. Length of the base of the first dorsal fin greater than the 
distance between the two dorsal fins, which is considerably less than the breadth across the cheeks at the centre 
of the eyes. 5 or 6 scales in a row from the end- of the first dorsal fin to the lateral line. No bare spot (ex- 
cept the anal aperture) in the median line of the belly. Scales carinated and spiny. Second- ray of the first 
dorsal- fin spiny, or ( in old, specimens ) at least granulated, on the front- surface; its length less than 2 / 3 of the 
depth of the body at its base. Length of the barbel under the chin about ’/ 3 of that of the lower jaw.

a According to Collett 21'3 — 1 8 ' 6 % in specimens between 538 and 935 nun. long. Perhaps the rule is that the head is smaller 
in the females than in the males.
