ICHTHYOLOGICAL COLLECTIONS OP THE ALBATROSS. 447 



which equal the length of liead without the 8iiout. Dorsal 44; anal 34; pectoral 42; 

 caudal 14. 



Colors in life: Olivaceous above, overlaid with light grayish. Belly and lower 

 side of head light yellow. Body and fins with large brownish-rod spots and blotches, 

 usually roundish, each having a darker margin surrounded with a light ring. 



A single specimen, 360 mm. long, from Bristol Bay (station 3252), in 29^ fathoms. 



105. Liparis fucensis sp. uov. 



Liparis caUiodon Garman, The Discoboli, Mem. Mus. Comp. Zool. xiv. No. 2, 

 p. 54 ; not Cychpterus callyodon Pallas. 



Numerous specimens dredged by the Albatross in the Straits of Fuca on a subse- 

 quent expedition (August, 1891) serve as the types of this species. It is probably the 

 same as that described by Garman as Liparis calliodon, his description being based 

 on specimens "said to have been taken near San Francisco." It is not evident from 

 the text whether the same specimens served as basis for the figures (plate vi, figs. 

 1-5), concerning which we have no separate data. 



Following is a description of the types from Albatross Station 3451, Straits of 

 Fuca, depth 106 fathoms : Moderately elongate, compressed ; head depressed, with the 

 gibbous snout and occiput separated by the depressed interorbital area which forms 

 a shallow transverse groove. Snout not blunt, the mouth terminal, nearly horizon- 

 tal, with included mandible, the maxillary reaching to or nearly to the vertical 

 from front of pupil, 3 in head. Teeth all tricuspid. Eye of moderate size, contained 

 5'§ in length of head, 1 to 11 times in bony interorbital Avidth, If times in snout. The 

 posterior nostril without tube, the anterior with a short tube, less than diameter of 

 pupil. Gill-slit comparatively wide, its width equaling length of snout and half 

 eye, overlapped by a conspicuous triangular prolongation of the opercle. The slit 

 extends down to opposite the upper third of the pectoral fin. 



Disk circular, of rather small size, distant from tip of snout 1^ times its own 

 diameter, from vent li times. Diameter of disk, 2f times in head. Distance from tip 

 of snout to vent, 1| to 1| in distance from tail. 



Pectorals extending to a vertical midway between vent and front of anal. Lower 

 rays produced, forming a narrow distinct lobe. The first 5 dorsal rays spinous, 

 unsegmented, shorter than the succeeding segmented rays, from which they are not 

 separated by notch. Dorsal and anal free from caudal, the last rays being rapidly 

 shortened, giving a rounded contour to the posterior portions of the two fins. 



Head 3^ to 3+ in length; depth 4 to 4|; dorsal v, 30; anal 28 or 29; caudal 18 or 

 20; pectoral 38 or 39. 



Two styles of coloration are observed : One, plain olive-brown, with minute dark 

 points, whitish below ; the other, with numerous narrow lengthwise streaks of 

 light olive and dark olive-brown, which extend forward on top and sides of head; 

 in both cases the belly is whitish and the fins dusky, mottled with darker, the 

 mottlings forming indistinct crossbars on the caudal fin. 



106. Neoliparis callyodon (Pallas.) 



Liparis mucosus Garman, The Discoboli, Mem. Mus. Comp. Zool. xiv, No. 2, p. 

 52; p. 52; not of Ayres. 

 Several young specimens were taken from under stones between tidemarks at 

 Unalaska May 24 and June 16, 1890. 



BATHYPHASMA gen. nov. 



A deep-sea Liparid, differing from typical members of the genus Liparis in having 

 the teeth long and slender, acuminate, sharp, with no trace of lateral lobes. The 

 ventral disk is large, and occupies the position usual in Liparis. An approach 

 to the condition here found is evident in J cftnocMr JHajor, in which, according to 

 Liitken, the teeth are at first tricuspid, becoming mostly simple with age. In 

 Bathyphasma the ventral disk is simple, without the intramarginal papilhe which 

 are usually present in Liparis and correspond to the tips of the spines and rays.
