somewhat projecting; maxillary rather broad, reaching* nearly to middle 

 of pupil, 2f in head Eye large, its diameter greatest obliquely down- 

 ward and backward ; equal to snout, 3| in head ; longitudinal diameter 

 shorter than snout, 3* iu head. Preorbitai rather narrow, its narrowest 

 place 2§ iu eye; its edge entire, sheathing the edge of the maxillary for 

 its whole length. Teeth very small, bauds wider than iu Xenistius call- 

 forniensis; those on vomer in a A-shaped patch, but very small. Nostrils 

 minute, close together, the anterior round, the posterior oblong. Seme 

 of preopercle at angle blunt, rather flat, none below, those on ascend- 

 ing limb smaller and sharper. Gill-rakers long and slender, about X-f 

 23. Opercle without spines. Cheeks and top of head with small scales ; 

 lower jaw and snout with rudimentary scales ; maxillary naked. Scales 

 small, firm, ctenoid. Dorsal fins entirely separate, the interval between 

 them about f diameter of eye. Dorsal spines rather high, slender, and 

 pungent; the first short, the third aud fourth of equal length, 2 in head, 

 reaching when depressed to the tip of eighth ; the second § of third. 

 Soft dorsal longer than anal, its base about f of an eye's diameter shorter 

 than that of spinous dorsal. Second anal spine noticeably shorter than 

 third, which is almost 4 in head ; longest soft ray 24 in head. Soft dorsal, 

 anal, and base of ventrals closely covered with small scales. Caudal 

 deeply forked, its peduncle slender, its upper lobe If iu head. Pectorals 

 long, pointed, If in head; ventrals reaching slightly more than three- 

 fifths distance to vent, If in head; axillary scale of ventrals well devel- 

 oped. 



Color grayish-black above, silvery below, with about 7 distinct, black, 

 straight, parallel stripes on back and sides which extend across opercles 

 and cheeks, those above lateral line indistinct in old specimens. The 

 upper stripes are about as wide as the interspaces, the lower narrower; 

 top of head with distinct stripes; fins dusky, except the ventrals. 



Numerous specimens of this beautiful and most graceful fish were ob- 

 tained at Charles Island. The species is named for Mrs. Jessie Knight 

 Jordan. 



15. Larimus pacificus sp. nov., {Larimus hreviceps of authors, from the Pacific coast ). 



Diagnosis. — Separated from the Atlantic species Larimus hreviceps 

 Cuvier, by the shape of the mouth, which is less oblique and similar to 

 that of L. fasciatus, by the small aual spine, 3 in head, and by the dis- 

 tance between origin of ventrals and anal, which is more than depth of 

 body, so that the ventrals do not reach vent. 



Type.— No. 41,1G8, U. S. National Museum.

Description.— Head, 3 (3f); depth same; D. X-I, 27; A II, G. Scales, 

 G-50-8. Length of type, oi inches. 



Body compressed, formed as in other species; back elevated, regu- 

 larly rounded from snout to last dorsal ray ; ventral outline most arched
