head as stated by Giinther, therefore a little shorter than in G. clupeiformis. Tongue 

 with 4 series of teeth, as in C. labradoricus. It seems to agree best with C. nelsoni 

 (description), but has fewer scales in lateral line. In short, I can not identify G. richard- 

 sonii with any of the forms known to me.

768(a). ABOYROSOMTJS ALASCANUS, Scofield, new species. 



Head4; depth about 4. D. 12; A. 12; scales 10-85-9. Eye a little 

 shorter than snout, 5 in head, 1 in interorbital space. Head wedge- 

 shaped, the upper and lower profiles straight and meeting with a sharp 

 angle at the snout. Viewed from above the snout is blunt, almost square, 

 with the narrow, pale rounded tip of the lower jaw slightly projecting. 

 Mouth oblique ; the distance from tip of snout to tip of maxillary is equal 

 to the distance from tip of snout to center of pupil ; the maxillary from 

 its anterior articulation is contained 3^ in the head, its width 3 in its 

 length, its upper anterior edge closing under the preorbital; inaudible 2 

 in head, its articulation with the quadrate bone beneath the posterior edge 

 of the eye ; width of supplemental bone a little more than ^ width of max- 

 illary. Preorbital broad, its greatest width equaling f its length or diam- 

 eter of pupil; width of supraorbital equals f its length. Gill rakers 12 

 to 14 -f- 21 to 23, long and slender, the longest | diameter of the eye. The 

 tongue, vomer, and palatines without teeth. Distance from tip of snout to 

 nape equaling the distance from nape to the front of the dorsal or 

 length of head. Adipose tin large ; ventral scale length of fin ; longest 

 dorsal ray 1^ in head; longest anal ray 2 in head; the pectorals reach 

 more than ^ to the ventrals; the ventrals reach f to vent; the caudal is 

 forked for a little more than its length. Color dusky above, silvery 

 beneath; the dorsal, adipose fin, tips of caudal rays and upper side of 

 anterior pectoral rays dusky; the rest pale. This species appears nearest 

 related to Argyrosomus artedi, from which it differs chiefly in the number 

 of gill rakers. * Length about a foot. Northern Alaska near Bering Straits ; 

 3 specimens known, 1 from salt water at Point Hope, the others from 

 fresh water at Grantley Harbor.

Page 482. Beginning with line 10 from the bottom, the statement that 

 the small form of the redfish has been traced from the mouth of the 

 Columbia to Wallowa Lake is not true. The remark was meant to apply 

 to the large form. The question as to whether the small form descends to 

 the sea is still unsettled. 



* The fin formulae, etc., of these 3 specimens are as follows :
