than in any of these, the caudal is not forked, the teeth are smaller. 

 The pectoral is a shade lower in insertion than in any of the living 

 SYNENTOGNATHOUS fishes. We may provisionally record it as the type 

 of a new family, FORFICID^E.

(Plate XVIII) 



This stout form of skipper (No. XXXVI) was found fossil in the 

 Elysian Hills of the uppermost Miocene formation in the hard sand 

 shale in the city of Los Angeles. The type was picked up by a student 

 and loaned by Dr. Charles L. Edwards for identification and description. 

 Only the head and a few vertebrae are preserved. 



Snout in head 1.15; depth of head at middle of opercle in head 2.56; 

 eye 12.82; no fins shown; body stout, elongate, cylindrical, covered with 

 oblong scales much larger than in S. ACUTILLUS or in the living S. SAURUS 

 of the Atlantic, each set with many concentric striae ; ribs weak and hair- 

 like; vertebrae comparatively weak, angularly diamond-shaped, 8^ in 

 25 mm. space ; without zygapophyses, and curved upward toward the 

 head; opercle deeper than long, sub-opercle small; upright limb of the 

 preopercle broad and vertical, rising to two-thirds height of opercle. 

 Jaws unequal, very strong, increasing in strength rapidly backward, set 

 with uniform teeth, stout, sharp, and strongly recurved, thirty-five teeth 

 in the space of 10 mm. below and weaker above and on adjoining parts. 

 Structures resembling teeth occur on the very ends of the jaws, and 

 structures resembling preorbital plates occur in the region between and 

 in front of the eyes. The mandible does not extend to the eyes. 



This specimen was probably over a foot long. It differs from 

 S. SAURUS in its shorter, stouter snout, stouter head and body, shorter 

 opercle, and the more nearly vertical upright limb. It is named for its 

 discoverer, a former student of the senior author, Dr. Charles Lincoln 

 Edwards, now in charge of science teaching in the graded schools of 

 Los Angeles. It was presented to Stanford University by Dr. Edwards.

This long-nosed skipper (No. XLIII) is from the diatomaceous 

 shale of the Miocene age at El Modena. The type was obtained by 

 Mr. E. E. Hadley. The anterior half only of the type specimen is 

 preserved. A second specimen (No. XLIV), four and a half inches 

 long, shows more of the body, but the head is crushed. Both are con- 

 sidered in this description, the first being the type. Head two and a third
