 Snout witie and tiepressetl, sharply \vedye-sha|x;d as viewed from the side; its lenj^h to a point <in iIk' 

 median line of head iK-tween anterior marjjin of eyes ,'^J to 4 in heail. The jjrefrontal does not form a 

 protuberance in front of eye as in (i. jordaiii m\A related s|)ecies, the contour of snout rising; uniformly 

 to the edfje of the dermal marj^in of eye. The interorbital area is flattened and wide; its width between 

 dermal supraorbital marj;ins 2 to 2 J in head. The to]) oi head is coarsely granular, the granulated area 

 estending forward usually to above middle of orbit in two diverging areas, se|j;irated by a triangular 

 continuation Ixickward of the naked or smooth area of .the snout. The length of the fontanel is 

 variable in the present specimens, but in none of them (U)es it reach the occipital |)rocess.' In two 

 specimens evidently abnormal, the groove is very short, extending only to the ape.x of the triangular 

 smooth area, which extends backward from interorbital space. Usually, howcser, the groove narrows 

 Ixickward uniformly, though sometimes constricted where it enters the granular area of the head, and 

 e.xtends to within J iliameter of eye of the occipital process. The occipital process is usually broader 

 than long; in e.xtreme cases it is broader than long by nearly the length of the basal plate of the dorsal 

 spine; from this it varies to only as broatl as long. The basal plate of the dorsal sjjine is twice, or a 

 little more than twice, as broad as long. The median keel is lower than in (i. planiccps or G. jordani; 

 in some S]x?cimens it is scarcely evident at the termination of tlie fontanel, hut grows stronger on the 

 occipital process. 



The ma.xillarv barbel usually reaches base of ])ectoral sjiine; in one s]K'cinun to axillary pore, 

 in several about to middle of ()])ercle. Tlu' outer mental barbels often reacli but \ distance to gill- 

 openings, but sometimes e.xttMid beyond the latter. The vomerine patches of teeth usually meet on 

 median line, or are separated by a narrow groove only. In but one specimen (an adult male) are 

 they widely se|>arated (as figured byGiinther and Eigenmann). The eye is contained 6^ to 7 times in 

 the head, measured in a straight line from median tip of snout obliquely above eye to gill-opening. 



As in other related species, the head is longer and the \entrals shorter in the male, the ventrals 

 overlapping front of anal in females and provided with a very large fold of the integument. In the 

 females the black of the ventrals passes gradually into the lighter margin. In males the transition 

 between the two areas is abrupt. In five specimens examined, the gill-rakers are 5-|-io, 5-}-io, 

 6+10, 5+11, and 5+12. The pectoral pore is a long slit. The jjase of adipose fin is twice or 

 nearly twice diameter of eye. The dorsal has 7 soft rays, and the anal 17 or 18. The length of 

 the jjectoral is \'ery variable; measuring from base of spine to tip of soft rays, it is contained from 

 I 5 to I i in head. 



I'^roiii G. jordani niid other fclated species, G. eigenmanni can be at once 

 recognized by the wider, flatter head, especially the more depressed snout, the smaller 

 eye, tiu- rougher liead, and the less evident carina on the occipital process. 



Three males and nine females were preserved. 



It is not clear what species from Santa Helena Bay is referred to by Boiilenger 

 (1 8U8-yy, Vol. Xnr, p. o) tnnler the name Avina seevKinni. From his statement 

 "Le Gnk'ichih>/!< (jl/hcrti Jord., n'en est pas separable," we are disposed to believe that 

 he had before him specimens of G. jordani rather than G. L'igen))ianni. 



33. Galeichthys jordani {Eigenmann <£■ Eigenmann). 



Two specimens were obtained 250 and 345 mm. long. The larger individual 

 is a female, with elongate ventrals overlapping the front of the anal fin, and provided 



' From n drnwing kiudly commuuicated by Professor Garman, it is learned that Eigeumauu's material in 

 the Museum of Comparative Zoology agrees with the present specimens in the length of the fontanel groove.
