jaws equal; maxillary reaching pupil, 3 in head; eye 5|; gill membranes 

 broadly united, their outline not notched; no trace of ventral tins; pec- 

 toral large, 2 in head (3 according to Giinther). Dorsal and anal joined 

 to the caudal, the anal with a slight notch behind the last ray; dorsal 

 spines short and all pungent. Color dark brown, clouded with darker; 

 about 11 quadrate pale areas along dorsal fin extending on the sides, these 

 areas each with a black central spot at tip and faintly marked with dark 

 blotches; dorsal with dark spots; a dark baud from eye downward, a pale

 branes pale orange ; caudal orange. Greenland. Here described from a 

 fine specimen, 9 inches long, in the U. S. National Museum, from Omaiiak 

 Fjord, Karsak, Noursoak Peninsula, taken in 1897 by Schuchert and White; 

 only the original type in the Senckenburg Museum hitherto known.

Anoplarchus, GILL, Proc. Ac. Nat. Sci. Phila. 1861, 261 (atropurpureus) . 



Body elongated, compressed, covered with very small, embedded scales 

 which ar.e obsolete or concealed anteriorly ; lateral line obsolete. Head 

 small, compressed; eyes small; mouth oblique; teeth in each jaw in a 

 narrow band, the outer somewhat enlarged ; narrow bands of teeth on 

 vomer and palatines ; gill membranes attached to the isthmus ; sometimes 

 with a free fold behind; branchiostegals 5. Dorsal fin not very low; no 

 anal spines ; .ventrals wanting ; caudal fin small, entire ; pectoral fins mod- 

 erate or small; pyloric cteca present, few. Pacific. (aroxAos, unarmed; 

 ap%o$, anus; the anal fin being without spines.) 



a. Gill membranes narrowly joined to the isthmus, with a free fold behind; dorsal with 

 about 63 spines. ALECTROLOPHUS, 2777. 



aa. Gill membranes broadly joined to the isthmus, without free fold behind; dorsal 

 with 54 to 57 spines. ATROPURPUREUS, 2778. 



2777. ANOPLARCHUS ALECTROLOPHUS (Pallas). 



Head 6 in length; depth 7|. D.LXII orLXIII; A. 43. Mouth oblique, 

 maxillary reaching vertical behind pupil, 2 in head. Teeth in narrow 

 bands on the jaws, the outer series in upper jaw somewhat enlarged; 

 vomer and palatines with narrow bands of teeth; dentition similar to 

 that in A. atropurpureus, which has been erroneously described as having 

 the teeth in the jaws in single series and the vomer and palate toothless; 

 gill membranes- rather narrowly joined to the isthmus and with a free 

 posterior edge slightly wider than pupil. A. atropurpureus has the gill 

 opening somewhat more restricted and the gill membranes without free 

 fold. Large pores on head arranged similarly in the two species. Spi- 

 nous dorsal beginning slightly in advance of base of pectoral, its distance
