MACRURUS COELORHYNCHUS. 
Fig. 139. 
Snout pointed, flattened, of a broad triangular shape, with sharp sides, which are continued by the carina of the 
suborbital ring ( the cheeks ) until they join the angle of the preoperculum ; length of the snout greater than the 
least breadth of the interorbital space, which is less than 1 / i (— 22*1 — 23*6 % in the specimens examined by us, 
which are between 18 and 25 cm. long) of the length of the head, than 4 / 5 (= 66'4 — 76*8%) of the longitudinal 
diameter of the orbits, than ' 2 / 3 (= 66*3 — 65 %) of the postorbital length of the head, than 1 / i (= 19*4 — 20*4 %) 
of the distance between the first dorsal fin and the tip of the snout, than 3 / 5 (= 56*9 — 54* 1 %) of the breadth 
across the cheeks at the centre of the eyes, or than (= 61*1 — 64 %) of the length of the lower jaw, which is 
less than or equal to 3 / 5 (= 35*7 — 39*1 %) of the length of the head, or about 1 / 3 (= 31*9 — 33*6 %) of the di- 
stance between the first dorsal fin and the tip of the snout, but greater than (in young specimens equal to) the 
postorbital length of the head. Mouth set on the under surface of the snout, its breadth at the corners less than 
2 / 3 (= 52*9 — 60*4 %) 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 — 85 % of the distance between the first dorsal fin and the tip of the snout, 
58 V 2 — 57 % of the distance of the second dorsal tin from that same tip, and 7 1 x / 2 — 67 % of the distance be- 
tween the anal fin and the tip of the snout. Depth of the body at the beginning of the first dorsal fin about 
14 — I 2 V 2 % °f the length of the body, at the beginning of the second dorsal fin about 10 % of the same. Pectoral 
fins lobate (with brachiate base). Length of the base of the first dorsal fin about 1 / s (= 57 — 51 %) of the 
distance between the two dorsal fins, which is about equal to the breadth across the cheeks at the centre of 
the eyes. 4 or 5 scales in a row from the end of the first dorsal fin to the lateral line. A narrow, oblong, 
bare spot in the median line of the belly between the ventral fins. Scales densely set with spines throughout 
the free surface , but without ccirince. Second ray of the first dorsal fin ( spinous ray) smooth; its height about 
equal to the depth of the body at its base or somewhat less. Length of the barbel under the chin about 1 / 3 
of that of the lower jaw. Jaw-teeth cardiform.
