 Prof. Robert CoUett (Christiania Vidensk. Selsk. Forh., 1879, 38) has assigned names 

 to the many color variations of Neoliparis inontagui as shown in Norway, as follows: 

 Yar. a. principalis, Collett, uniform colored; light red yellow with microscopic brownish 



dots. The common form from Christiania, Stavanger, Flor., onear Bergen, Komags- 



bjord in Fiumarkon. Liparis inontagui, Malm, Gotheborg og Bohuslans Fauna, 451, 



1877. 

 Var. b. maculatus, Malm, dark grayish yellow, the whole body strewn with many rows 



of small brown spots, smaller than the eye and sharply defined. Bukn and Bohuslan. 



Liparis maculatus. Malm, Forh. Skand. Naturf., 9, 1803, 412. 

 Var. c. annulatus, Collett, reddish gray yellow, with large, irregular red-brown rings of the 



same length and breadth ; on sides of head the rings becoming stripes ; Christiansand. 

 Var. d. striatus, Collett, color of c, the rings drawn out into lines ; the rings only seen in 



front of first dorsal ; about 6 longitudinal red-brown stripes from gill opening to caudal. 



Bergen. Liparis lineatus. Malm, Forh. Sk. Forh., 9, 1863, 412. 

 Var. e. pictus, Collett, as in striatus, but the lines very numerous, close set, irregularly 



vermiculate, with much cross netting or partial rings. Bergen. Finmarken. 

 Var. f . obscurus, Collett, gray brown with many dark brown spots and specks on body and 



fins ; irregular cross bands on caudal ; back almost uniform gray brown. Hardanger 



Fjord. 

 Var. g. liparoides, Nilsson, uniform dark gray brown, the color given by innumerable dark 



points ; trace of band at tip of caudal ; paler below. Hardanger, Get jord in Finmarken 



Tromso. Cyclopterus liparoides, Nilsson, Prodr. Ichth. Scand., 62, 1832. 

 Var. h. ekstromi, Malm, dark brown, sides strewn with grayish yellow small spots which 



extend on vertical fins. Bohuslan. Liparis ekstromi, MaT.m, Fork. Sk., Naturf., 9, 



1863, 412. 

 The.se are evidently mere color forms, expressing the range of variation. Similar color 

 forms may be seen in most of the bright-colored species, pulchellus, agassizii, alcuticus. 

 They are not in any proper sense subspecies, having no geographical bases or separate 

 lines of descent. 



2443. XEOLIFIKIS BUTTERI, Gilbert & Snyder, new species. 



Head 3f ; depth 4^. D. VI, 26; A. 23; P. 30; eye 5 in head; snout 2|; 

 voutral disk 1^. Body widest at gill opening, gradually tapering poste- 

 riorly, deepest below third dorsal spine; depth of caudal peduncle 4 in 

 head. Head broader than deep, its depth at occiput 6 in body. Mouth 

 narrow, its cleft almost wholly transverse, extending to vertical from 

 anterior nostril; lower jaw included; teeth tricuspid, the middle cusp 

 highest, arranged in 10 oblique series on each half of the upper and the 

 lower jaws. Gill opening very narrow, restricted to the area above base 

 of pectoral. Anterior nostrils tubular; posterior nostrils with a low rim, 

 the anterior part of which is elevated into a triangular flap. Skin loose, 

 lying in folds and wrinkles. Origin of dorsal at i the distance from tip 

 of snout to caudal ; rays of first dorsal (in the types which are apparently 

 all males) separate almost to base, each ray bordered with a thick mem-
