264 DEEP-SEA FISHES OF THE ATLANTIC BASIN. 



»S'. Giintheri,^ with a shorter aud higher dorsal, a sliorter, more I'oiuided pectoral, with the 

 ])reorbital spines aiitrorse aud the i)reopercular si)iues slenderer, more uuitbriniii size, more 

 divergent, and four in number. The four ridges of the vertex terminate each in i. sharp 

 spine, visible from the lateral aspect.

A iSetarches having head and body .short and somewhat eompressed; the height of the 

 body over ventrals greatest, and contained about 2i in total length (without caudal) length 

 of head 2J in length of body. 



Head somewhat comj)ressed. Width of interorbital area equal to diameter of eye, 

 which IS somewhat below the profile. Ridges on top of head low and inconspicuous; two 

 extending to the occiput, where they terminate in low, flat spines; two short ones over the 

 posterior margin of orbit, ending in .spines slightly behind the orbit. Snout fis long as the 

 orbit. Mouth wide, somewhat oblique; maxillary with a considerably expanded posterior 

 extremity, reaching nearly to the vertical from posterior margin of orbit. Lower jaw 

 scarcely projecting, and without i)romiuent knob at symphysis. Sides of head lightly 

 armed, there being four slender, elongate spines on the preoperculum ; the edge of the sub- 

 orbital is broadly scalloped with two points projecting in downward direction opposite the 

 anteiior and posterior margin of the orbit. Spines on the operculum small and inconspic- 

 uous. Two slender spines upon the preorbital, the anterior one touching the opening of 

 the mouth. Head scaleless save upon the operculum, pre- and suboperculum. Scales 

 small, cycloid, each with several concentric furrows. Lateral line broad, scaleless, with 

 skinny tubes, of which there appears to be about 30 (an exact count not possible) ; the 

 lateral line is practically concurrent with the line of the back. Dorsal in.sertion in advance 

 of that of pectoral; the first sinne more than half as long as second, and equal to ninth; 

 the second as long as the seventh; the third and fourth about equal, and a little longer 

 than the maxillary; the fifth, sixth, seventh and eighth gradually decreasing. There are 

 12 spines and 10 soft rays, the fin being deeply notched. 



The type, as the drawing indicates, is somewhat deformed, owing to an accident in life, 

 but a comparison with the other related species enables us to judge very nearly of what its 

 shape must have been. Anal inserted under posterior part of soft dorsal, with 3 spines 

 and 5 rays, the longest of which — about equal to the last spine — are as long as the 

 second dorsal. Ventral in vertical from root of second dorsal spine, with 1 spine and 

 5 rays, its tip not reaching to vent, which is close to origin of anal. Pectoral broad at 

 its base, elongate, some of its median rays apparently branched, its tip extending beyond 

 the origin of the anal.
