826. EVERMANNIA, Jordan. 



Evermannia, JORDAN, Proc. 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. Yentrals formed as in GoUus and Gobio- 

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

 sand and mud between tide marks. (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 work on 

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

ZOSTEEUBA, 2589. 



2688. EVERMANNIA LONGIPINNIS (Steindachner). 



Head 3; depth 5 to 5fr. 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 very 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 4f 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 Evermannia, with which 

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

 It may be the type of a distinct genus. It differs from Clevelandia in the 

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

 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."
