12 FOSSIL FISHES OF LOMPOC 



as figured by Jordan and Gilbert. It is, however, unquestion- 

 ably a member of this species. The dorsal, pectoral, and ventral fins 

 are fairly preserved, as are also the vertebrae and the ribs. There are 

 eight vertebras before the ventrals. Ribs about 22. Vertebrae rather 

 deeper than long, those anteriorly a little elevated. 



Other specimens are the following: 



29. Probably the same, body only, anterior vertebrae out of place. 



44. Vertebral column little arched; pectoral complete, short, 2y 2 in 

 head; about 15 scutes before ventrals. 



124. Fair; head large, broken; ventrals a little nearer gill opening 

 than base of caudal. Caudal well forke'd, anterior vertebrae moderately 

 arched, vertebrae 45, dorsal and anal wanting. 



140. Young the vertebral column little arched. Vertebrae about 

 40 poor condition. 



507. In fair condition, much like No. 26. The backbone not arched, 

 but undulated. 



146. Column a little arched; paired fins wanting. 



149. Bad order ; column little arched. 



150. Broken head. 



196. An example with a big head, deep body, and .median dorsal. 

 Vertebrae about 40. the column somewhat arched anteriorly: belly with 

 strong scutes. 



244. Broken torso, showing 15 ventral scutes. 



235. Shows a short dorsal nearer head than base of caudal; spinal 

 column little arched, broken, apparently very fragile. The whole struc- 

 ture very weak. 



274. Broken torso, vertebral column somewhat arched. 



278. Part of a large example. No new features. 



291. Part of side no arch in vertebral column. 



314. Broken skeleton and head. The vertebral column a little arched 

 anteriorly. 



324. Head and torso much broken. 



411. Fair condition; shows ventral scutes and paired fins. Head 

 large, 3y 2 in length, depth 3 ; 13 scutes before ventrals. 



In addition to those noted above there are numerous fragments more 

 or less definitely referable to this species. 



4. Lygisma tenax Jordan and Gilbert. 

 No. 79. Seven inches long. 



Head and vertebral column, the head badly crushed, the vertebral 

 column intact and much twisted as in the original types: neural and
