Walb.) is very great; hence its name of " Sardina de Espana," ainoug 

 the Cabau fishermen. 



Head 4^ to 4 J in length; depth 5 to 5.^; D. IG, A. 10: hit. 1., about 45. 



Body slender, little compressed, the belly scarcely carinated, its scutes 

 not prominent; mouth small, the maxillary not extending quite to front 

 of pupil, its length 2| in head ; gill-rakers long, very slender and numerous, 

 about two-thirds diameter eye, between 30 and 40 on arch below angle. 

 Lower jaw with a few feeble teetb, visible with lens; tongue with some 

 asperities; cheeks much longer than deep, the vertical depth below eye 

 about two-thirds diameter of eye ; eye 3| in head. Opercle without 

 distinct stria? ; interopercle with very few. Ca udal well forked ; the lower 

 lobe a little the longer as long as head. Yentrals inserted nearly be- 

 low middle of dorsal, a little nearer base of caudal than tip of snout ; pec- 

 torals 1^ in head ; a conspicuous sheath of scales at base of pectorals. 



About 45 scales in a longitudinal series; the scales being thin and 

 deciduous, their number cannot be exactly ascertained.

 tinct markings anywhere. 



reritoneum pale; lining of oi^ercle somewhat dusky. Intestinal canal 

 somewhat elongate, about li times length of body. 



This species is mostly readily distinguished from G. piJcJiardus by the 

 absence of radiating striae on the opercles, these being very conspicuous 

 in the sardine. 



DOROSOMATIDiE. 



17. Dorosoma cepedianum (Le S.) Gill.— Shad. G. (30913.) 



Generally abundant, especially along the coast of Texas. The speci- 

 mens all differ somewhat from the usual form of this species, and appa- 

 rently constitute a local variety or subspecies, xjerhaps worthy of a dis- 

 tinctive name. Compared with i^pecimens from White Kiver, Indiana, 

 the Galveston form has a slenderer body (depth 'S^ to 3 in length, in- 

 stead of 2J to 2|), and larger head (4 in length, instead of 4^). The 

 dorsal filament is in all specimens shorter th;!n the head. There seem 

 to be no other permanent diftereuces. D. 12; A 1, 32. Scales 5G to 20. 

 Scutes 18 + 12. 



This species is not used for food. It must spawn in or near the sea 

 at Galveston, as individuals of all sizes are abundant in the baj
