concave, witli rough plates; supraorbital ridge ending in a blunt tubercle; 

 interorbital area with smooth skin. Eyes very large ; maxillary extend- 

 ing to pupil; upper preopercular spine broad; much shorter than eye, 

 with about 3 points; skin mostly smooth; axil prickly, but without 

 fringed filaments; inner edge of middle pectoral rays papillose (male). 

 Spinons dorsal very high and long, the longest spines in the male f length 

 of head; second dorsal a little lower; anal very long, rather low; pec- 

 torals very broad, reaching past front of anal, the lower rays rapidly 

 shortened; veutrals extremely long, the rays long, exserted, reaching past 

 front of anal; anal papilla large. Dark brown above, with traces of 

 darker vertical bars; belly pale; males with the axillary region dusky, 

 with many large round white spots; first dorsal blackish, with pale 

 blotches; second dorsal with alternating oblique bands of white and 

 blackish; anal and caudal nearly plain; pectorals and ventrals yellowish, 

 with black cross bars; mandible barred with black. Arctic seas, south 

 to Norway and Labrador ; not very common on our coasts. Here described 

 from a specimen from Greenland. Dr. Giinther gives the following ana- 

 tomical details: "The liver is large, round, not divided into lobes, and 

 situated principally on the left side of the stomach. The stomach is very 

 spacious and curved; the pylorus with 6 appendages; the inte&tines 

 appear to make 1 complete circumvolution. The ovaria are separated 

 from each other to their posterior extremity. The urine bladder is nar- 

 row, elongate, situated above the right-hand ovarium. Skeleton: The 

 configuration of the skull is much more similar to C. goMo than to C. scor- 

 pius or Imbalis. The space between the orbits is very slightly concave, 

 very narrow, its width being nearly ^ the distance between the upper 

 posterior angles of the orbits. The crown is flat, without any longitudi- 

 nal or transverse ridges, but with very slight impression in the middle. 

 The frontal bones, the preoperculuin, the mandibula, and the infraorbitals 

 have very distinct muciferous channels; the turbinals are provided with 

 a minute spine. The number of the caudal vertebrae is increased, there 

 being 12 in the abdominal portion and 28 in the caudal." (Eu.) (tres,
