2. Calycilepidotus lateralis. 

 (Syn. Scorpcenichthys lateralis, Gir.) 



As this species has been already described by Mr. 

 Girard (loc. cit.) a detailed account of it here is not 

 needed. It has the scales in a single band on each 

 side, corresponding in some degree with the first band 

 of the spinosus, but less regular, and not connected 

 in the same manner in front of the dorsal fin ; small, 

 scattered scales are found also on the head. The 

 head is less spinous, though the upper spine of the 

 preoperculum is stronger and branched. The divis- 

 ion of the spinous and soft dorsal is so complete, that 

 they may be called two fins, though contiguous. — 

 The membranous flaps of the head are extremely 

 small ; one at the superior posterior border of the 

 orbit, and one at the extremity of the maxillary, 

 both very difficult to detect in alcoholic specimens ; 

 none at the symphysis of the lower jaw. The eye is 

 decidedly smaller than in spinosus. The gill-open- 

 ings are continuous. 



C. lateralis is perhaps a little more common in the 

 Bay of San Francisco than C. spinosus, which it 

 about equals in size. Mr. Girard's specimens were 

 oollected at Monterey and San Luis Obispo.
