 with about 3 points; skin mostly smooth; axil prickly, but withoiit 

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

 Spinous dorsal very high and long, the longest spines in the male f lengtli

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

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

 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 jiylorus with 6 appendages; the intestines 

 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 oA-arium. Skeleton : The 

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

 piiis or huhalis. The space between the orbits is very slightly concave, 

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

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

 nal or transverse ridges, but with A-ery slight impression in the middle. 

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

 haA'e A'ery distinct muciferous channels; the turbinals are provided with 

 a minute spine. The uumlier of tlie caudal A^ertebra^ is increased, there 

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