Eose-red or brownish, unspotted. Body strongly compressed, the 

 back somewhat elevated, not much depressed forwards, the head not 

 wider than deep, longer than in L. fuJcliella ; mouth rather large, 

 terminal, the jaws equal when closed; teeth blunily tricuspid, the 

 band in upper jaw widest; eyes small; skin iirm, thick, little movable. 

 Dorsal tin separated iuto two parts by a deep emargination; second 

 dorsal rather low, entirely free from caudal ; anal nearly free from 

 caudal; pectorals moderate; ventral disk oval, 2.^ in head; vent at 

 posterior fourth of pectorals; end of tail truncate. Head 4J; depth 

 about 4. D. VII, 2G; A. 26; C. 16; P. 31. L. 6 inches. Coast of Cali- 

 fornia; rare.

[The Lump SucJcers.) 



Body short and thick, more or less elevated, covered with a thick 

 skin, which is smooth, tubercular, or spinous; head short and thick; 

 suborbital stay present, thin and Hattish; mouth small, terminal; jaws 

 with bands of slender teeth; no teeth on vomer or palatines; gill- 

 opeuings narrow, restricted to the sides, the membranes being broadly 

 joined to the isthmus and shoulder girdle; branchiostegals 6; dorsal 

 tin long, the anterior i)art of flexible spines, which, in the adult, are 

 sometimes hidden by a fleshy hump, sometimes entirely wanting; 

 soft dorsal small, opposite the anal, and similar to it; caudal fin 

 rounded, free from the dorsal and anal; ventrals thoracic, rudimentary, 

 forming the bony center of a sucking-disk; pectorals short, placed low, 



*In Dr. GUnther's type of L. cydopu?, from Esqnimanlt Harbor, the fiu-forninhi is 

 D. 35; A. 30; C. 12; the ventral disk is said 1o be less than half the length of the 

 head, arid the dorsal is said to begin behind the vent. The species is said to agree 

 .'in nearly every respect with L. vulgaris" {lituaia). Our specimen is much Jieaier 

 L. mucosa.
