to the nape, the region thence to the dorsal gibbous, especially iu the 

 larger examples, the caudal peduncle comparatively long and slender, 

 about as long as head. 



Anterior teeth large, firmly fixed, all bicuspid or Y-shaped, in a single 

 series; a band of minute villiform teeth behind them, at least in upper 

 jaw. Mandible not extending back to front of eye. Eye rather large, 

 3^^ in head, Interorbital area wide, very nearly half head. 



Scales rather small, those on top of head not much larger than the 

 others; humeral scale not enlarged. Opercle connected by membrane 

 to shoulder girdle, from upper base of pectoral upward, as in Cijprinodon. 

 Insertion of dorsal very fiir back, midway between base of caudal and 

 base of pectoral. First ray of dorsal very slender and articulate, not 

 at all spine-like. Dorsal fin low, not so high as long, its base 1§ iu 

 head. Anal inserted below seventh ray of dorsal. Pectorals 1% in 

 head; ventrals 2. Caudal obliquely truncate, very slightly emarginate, 

 the upper lobe about one fifth longer than the lower, 1^ in head ; upper 

 lobe usually more or less sharply angular; lower lobe rounded. 



Coloration in spirits: Males with the sides profusely mottled with 

 darker, sometimes nearly plain. Vertical fins each with several brown- 

 ish bars and blotches and each with a dusky subterminal bar. A nar- 

 row dark line along middle of each row of scales on the back. Females 

 with several short dark bars on the posterior half of the body, the fins 

 colored as in the male. Some small dark specks on caudal peduncle. 



7. Fundulus parvipinnis Girard. 



7242. Numerous examples, precisely like others from San Diego. 



8. Fundulus vinotus, sp. nov. 



30973. One specimen, somewhat faded, but in fair condition. Length 

 2i inches. Head 3f in length; depth ^. D. 12; A. 11. Scales about 

 31-10. 



Body little elongate, compressed posteriorly. Head large, very broad, 

 and somewhat depressed above. Mouth moderate. Teeth in narrow 

 bands, the outer much enlarged. Eye 3^ in head. Interorbital space 2. 



Scales comparatively large. Dorsal inserted moderately in advance 

 of anal, its front midway between base of caudal and occiput ; the fin 

 of moderate height. Pectoral If in liead ; caudal 1|. 



Coloration, in spirits, olivaceous, with about 23 narrow silvery bars 

 with undulating edges, the bars narrower than the darker interspaces. 

 Fins now all plain. 



This species is apparently related to F. hetcroclitus and other Atlantic 

 species. It may be distinguished from most of its relatives by its com- 

 paratively large scales. 



9. Fundulus extensus, sp. uov. 



30972. Two specimens, faded and rather soft, the longest nearly 3 

 inches long. 

 Head 3^; depth 5|-. D. 15: A. 13. Scales about 17-12.
