MERLUCCIIDAE 49 



Depth of body 5 to 6 in the length, length of head 3 J to 3§. Snout more than twice 

 as long as eye, diameter of which is 6 to 7^ in length of head ; interorbital width 3§ to 

 nearly 4. Maxillary extending to below hinder edge of pupil (posterior edge of eye in 

 adults), length about I that of head. 10 gill-rakers on lower part of anterior arch. 

 155 to 165 scales in a longitudinal series below lateral line. Dorsal 11, 36-43; anal 

 36-42. Pectoral with 13 rays, extending to vent or beyond, length if to if in that of 

 head. Pelvic extending £ to § of the distance from its base to the vent, length 2\ to z\ 

 in that of head ; insertion of pelvic nearer to origin of anal than to tip of lower jaw. 



Hab. New Zealand ; Straits of Magellan. 



Described from 3 specimens, 340-435 mm. in total length. 



This species is readily distinguished from the other members of the genus by the 

 smaller scales. I am unable to detect any important differences between the specimen 

 collected by the ' Challenger ' in the Messier Channel (Magellan) and those from 

 New Zealand. 



Genus Macruronus, Glinther 



Macruromis, Glinther, 1873, Zool. Record, for 1871, p. 103; Giinther, 1887, Deep-Sea Fish. 

 'Challenger' , p. 157. Type Coryphaenoides novae-zelandiae, Hector. 



The firm attachment of the first vertebra to the skull, and the separate frontal bones, 

 with ridges diverging from the occipital crest and bordering a large triangular de- 

 pression, place this genus in the family Merlucciidae. It differs from Merlnccius in the 

 tapering tail without caudal fin.
