826. EVERMANNIA, Jordan. 



Evermannia, Jordan, Troc. Cal. Ac. Sci., iv, 1895, series 2, 592 {zosterura). 



Body slender, compressed behind, entirely naked. Head long, slender. 

 Snout rather pointed; mouth moderate, terminal, the maxillary more or 

 less produced backward ; teeth small and slender, the outer above slightly 

 enlarged. Skull with a small median crest, not much widened behind. 

 Interorbital space very narrow, channeled ; no dermal flaps on shoulder 

 girdle; first dorsal of 4 to 6 spines; second dorsal and anal long, of 14 or 

 15 rays. Caudal lanceolate. Ventrals formed as in Goiiiis and Gobio- 

 soma. Size small, the sexes not colored alike. Species living in holes in 

 sand and mud between tide mai-ks. (Named for "my former student and 

 later scientific associate, Dr. Barton Warren Evermann, now ichthyolo- 

 gist of the United States Fish Commission, in recognition of his Avork on 

 the fishes of the Gulf of California." — Jordan.)

2588. EVERMANNIA LONGIPINNIS (Steindachner). 



Head 3*; depth .5 to 5J. D. IV to VI-16 or 17; A. 16 or 17; snout 

 slightly decurved in profile, 3^ in head; eye 6, greater than interorbital 

 width. Body Aa^ry slender. Mouth somewhat oblique, the jaws equal; 

 maxillary extending beyond middle of head to a distance behind eye 

 equal to diameter of eye. Teeth in each jaw in 2 series laterally and 3 in 

 front, those of the outer series somewhat enlarged. Fins low, the longest 

 dorsal spine 2 in head; pectoral a little shorter than caudal, scarcely 

 longer than ventrals. Caudal rounded, shorter than head, probably 4j in 

 body. Body and head completely naked.* Brownish yellow; upper 

 parts of head and body with small, irregularly placed brown spots and 

 streaks; dorsals and caudal finely barred with dark specks. (Steindach- 

 ner). Gulf of California; not seen by us; known from 3 specimens 37^ 

 mm. long. We refer this species provisionally to Evcrmannia, with which 

 genus it agrees in external respects, although the mouth is much larger. 

 It may be the type of a distinct genus. It difters from Cleoelandia in the 

 entire absence of scales, {longus, long; pinna, fin.)

Head 3^; depth 6. D. IV-15; A. 14; eye equals snout, 5 in head; P. 1|; 

 C. li. Body compressed, profile convex; snout short, not very blunt; 

 eyes high, the maxillary reaching to their posterior margin; mouth 

 oblique, jaws equal; first spine of dorsal filamentous, reaching to middle 



" At our request Dr. Steindachner has reexamined the types of this .species. He still 

 finds them " vollkommen schuppenlos."
