D. v. 8; A. 6 ; P. 23; V. i. 5 : 0. 6. Head, measured from 



the middle of the upper jaw to the anterior edge of the gill- 

 Opening, 1.93 in the length to the hypural ; its width 1.71 in 

 the same, and much greater than its length. Width of the 

 mouth 1.3 in tin' head or 2.52 iu the length. Snout o.34 in the 

 head. Enterorbital 1.53, eye-opening 3 in the snout. Greatest 

 depth just behind the ventrals 4.65, length of pectoral 4.8, 

 caudal 4.25 and first dorsal spine 4.3* in the length. 



Body covered with soft loose skin, all the upper parts with 

 minute pores set iu dark-edged ocelli, the larger of which bear 

 blackish skinny appendages. A lateral line, consisting of a 

 series of pores, extends from the back of the head, in a curve 

 above the gill-opening, to the side of the tail where it is lost ; a 

 branch extends over the back at the base of the third dorsal 

 spine, and another runs downward onto the sides of the head and 

 branches out over the opercles. The sides of the head and tail 

 hear numerous rather long branched tentacles. Upper margin 

 of the orbit with two blunt spines, the posterior of which is the 

 largest ; directly behind the eye is a third, followed by anothei 

 smaller one placed a little nearer the median line of the head. 

 A large tubercle on either side of the temporal region above the 

 point of suspension of the operculum. Humeral spine tritid, with 

 a short supplementary basal spine. A minute spine is present 

 on each side of the prcmaxillary symphysis, and there are two 

 larger, diverging ones exterior to the nasal papilla. The hinder 

 margin of the preoperculum bears a small spine, and two others 

 occur on its lower margin just behind the maxillary. The outer 

 anterior angle of the operculum ends in an acute spine, which is 

 followed by one or two small teeth, and a second spine projects a 

 little further back on the upper surface. Most of the spines of 

 the head are normally covered by the skin and are difficult to 

 see. 



The gill-openings are very wide, and commence just above and 

 in front of the anterior borders of the pectorals. They extend 

 under and behind those tins, and their skinny margins terminate 

 in broad free Haps on the sides. The opercles have no real free 

 borders as in other species of Chirolophius.
