Stelgis, CRAMER, Proc. Cal. Ac. Sci. 1895, 821 (vulsus). 



Body tnpcrino-, depressed throughout, its height about 8, its breadth 

 about 7 in its length; head 4, depressed. Plates of body spinous, about 

 37 in dorsal series; only about 8 median plates on peduncle; 7 pairs between 

 occiput and iirst dorsal. Month inferior, snout projecting beyond pre- 

 niaxillaries ; teeth on jaws, none on yonier or palatines. One pair of hori- 

 zontal and 1 pair of recurved spines at tip of snout. Scattered barbels or 

 cirri on maxillary, inaudible, and branchiostegal membranes; a few on 

 under side of snout, or none. One pair preocular, 1 pair supraocular, and 

 2 (4) pairs occipital spines. A transverse pit at occiput. Brauchiostegal 

 membranes joined to isthmus. (tiTzkyic,, or tfrksyyis, a scraper.)

B. 6; D. IX, 7; A. 9; P. 14; V. 3 (1, 2). Body elongated, tapering rapidly 

 backward, depressed throughout, height $ of breadth, the latter about 7 in 

 length of body. All plates of body armed with spines except thosein anterior 

 and posterior parts of the ventrolateral series ; spines strong and recurved. 

 Only about 8 plates in median dorsal series of tail, but the spines of the ridge 

 continue, double. At base of tail on each side is a spine, between the lateral 

 ridges ; vent just behind middle of length of ventrals. Lateral line about 

 40. Ventral surface flat throughout. Head acutely triangular (seen from 

 above), depressed, depth about f- of width, the latter about 5J in length of 

 body; length of head about 4; profile irregularly sigmoid, depressed at front 

 of eyes,thence nearly straight to tip of rostral spines. Mouth V-shaped, infe- 

 rior ; maxillary reaching front of pupil ; snout projecting anteriorly beyond 

 preinaxillaries. Teeth in bands on jaws, none evident on vomer or pala- 

 tines. Maxillary, mandible, and branchiostegal region with small, scat- 

 tered cirri ; under side of snout with few barbels or none. Eye large, nearly 



* Diagnosis: Body tapering, depressed throughout, height about f of breadth, the latter 

 7 in length of body. Body spinous; only about 8 med^in plates on peduncle. Head 4; 

 plates in dorsal series about 37 (number between last ray of second dorsal and first 

 median plate not recorded ; all others 34) ; between occiput and first dorsal 7 ; between 

 membranes of dorsal 4. Gill membranes joined to isthmus. No teeth on vomer or pala- 

 tines. Scattered barbels on maxillary, mandible, and branchiostegal membranes; a few 

 on under side of snout, or none. One pair of horizontal and 1 pair of recurved spines on 

 snout. One pair preocular, 1 pair supraocular, and 2 (or 4 ?) pairs of occipital spines. 

 Bark brown, with 7 to 9 cross bars ; fins mostly dark.
