in Baailichthys* 67 to 75 in a lengthwise series. Coast of California. 

 (/Ifi'pof, smooth ; hadtu, to eat ; from the toothless jaws.) 



a. Scales about 67; lateral band not so wide as eye. cramebi, 1171. 



aa. Scales about 75 in longitudinal series; lateral silvery band wider than eye. tenuis, 1172. 



1171. LEUBESTHES CRAMEBI, Jord.an A Evermann, new species. 



Head 4f ; depth 5i ; eye 3f ; snout 3^. D. V-I, 8 ; A. I, 21 ; scales 

 5-67-6. Body slender, gently rounded above, narrowed below. Scales 

 smooth, firm, closely imbricated, the membranous edge strongly serrate. 

 Mouth moderate, premaxillaries very protractile; maxillary short, not 

 reaching eye. First dorsal over front of anal, much nearer base of 

 caudal than tip of snout, or midway between base of caudal and gill 

 opening. Color hyaline green, Avith a lateral silvery streak, plumbeous 

 above, narrow, its width \\ in eye, wider than one row of scales, cover- 

 ing one row and two half rows; body above lateral line covered with 

 small brown specks ; pectorals and caudal chiefly blackish ; second 

 dorsal with many black specks ; anal and ventrals plain. Close to 

 Leuresthes tenuis, from which it differs in the larger scales, smaller eye, 

 shorter maxillary, and the much narrower lateral band. Length 5 

 inches. Ballenas Bay, Lower California, near Cape Abreojos. Several 

 specimens collected by Dr. Charles H. Gilbert, on the Albairos>i. (Named 

 for Frank Cramer, in recognition of his excellent work on the Scor- 

 panidcv and Agonidw.) (Type, No. 27, L. S. Jr. Univ. Mus.)

Head 4i ; depth 5. D. V-I, 9 ; A. I, 22 ; scales 75. Eye equal to 

 snout. Scales small, smooth, and fii-m, closely imbricated, their edges 

 crenate. Maxillary not reaching to pupil. Premaxillary very protract- 

 ile, curved, its posterior portion broad. Lower jaw shorter than upper ; 

 soft dorsal and anal scaleless. First dorsal fin over front of anal, much 

 nearer base of caudal than snout. Clear hyaline green, with the lateral 

 silvery streak very distinct bluish, wider than eye, on li rows of scales ; 

 edges of scales above bordered by dark points. Length 5 inches. Coast 

 of California from San Francisco to San Diego ; abundant in San Diego

358. EURYSTOLE, Jordan & Evermanu. 



Euryslole, Jordan & Evermanx, new genus, (eriarcha). 



This group differs from Menidia chiefly in the very long anal liu; the 

 spinous dorsal is very small, the scales smooth, the breast not compressed, 

 the pectorals short, and the head short and deep ; the mouth is formed as 



* BasUichthijs, Girard, the characteristic genus of the coast of Chili, differs from Mi-nidia in the 

 very small scales (75 to 105). Some of the species reach a large size and are valued as food. The 

 teeth in Basilichlhijs are well developed.
