Under parts immaculate; the mottlings along base of dorsal frequently 

 uniting to form a series of oblong blotches alternating with those of lateral 

 line ; other specimens show no traces of dorsal blotches ; dorsal fin trans- 

 lucent, faintly mottled with darker; caudal with brownish cross bars; 

 pectoral with a round dusky shade at base; fins otherwise unmarked. 

 Mandible with a single series of conical teeth, which widens at symphysis 

 into an irregular double series or narrow patch ; a similar series of conical 

 teeth in premaxillaries, within which is a band of fine villiform teeth. 

 A number of small specimens from Disco, Greenland, are entirely similar 

 except for the darker coloration. This species is near L. angtiiUaris, but 

 the latter has a larger mouth, larger teeth, and more numerous fin rays. 

 (Named for Otho Fabricius, the first student of the fishes of Greenland.)

2794. LUMPE\US LAMPETRJEFORUIS (Walbaum). 



(SNAKE BLENNY; TANGBROSME.) 



Head 9; depth about 15. D. LXXIII (LXVIII to LXXIV); A. 50 (49 

 to 52) ; V. I, 3. Body elongate, head slender ; lower jaw little shorter than 

 upper ; maxillary reaching front of eye. Vent well forward, near end of 

 first third of body; pectoral convex, somewhat shorter than head; first 

 3 or 4 rays of dorsal short, little connected; caudal acuminate, free from 

 dorsal and anal. Yellowish or greenish, with numerous (about 20) faint 

 brown blotches of different sizes, some of them confluent and extending 

 obliquely upward on dorsal; caudal with transverse dark shades. (Col- 

 lett.) North Atlantic and Arctic on both shores, south to Sweden and 

 Norway, east to Spitsbergen ; rare south to Cape Cod, if L. serpentinus is 

 the same. We can find no difference on a comparison of our notes with 

 published figures and descriptions, except that Storer describes serpentinus 

 as having the caudal plain yellowish. (Eu.) (Lampetra, lamprey; forma,
