condition, taken in Elliot Bay, near Seattle, received from the Yonng 

 Naturalists' Society. They are numbered 3126 in the register of the 

 Leland Stanford Jr. University Museum. This siiecies, not having been 

 previously recognized since its original descri]5tion, is recorded by Dr. 

 Gilbert from Unalaska, and 2 specimens from Bristol Bay, Alaska (Jlha- 

 iro88 Station 3230, depth 3^ fathoms). Garman places L. cyclopns in the 

 synonymy of L. calhjodon, but our specimens are undoubtedly distinct 

 from the species described by Garman under this name (Discoboli, ji. 54, 

 pi. 6, figs. 1-5), from a specimen said to originate from San Francisco. 

 Our Alaska specimens are much more slender, with Avide depressed head, 

 without nuchal elevation, with the dorsal fin beginning posteriorly 

 slightly in front of the vertical from the vent, and the disk separated from 

 the vent by a distance less than its own diameter. The mouth is also 

 much smaller, not at all oblique, its angle in advance of vertical from front 

 of eye. Not yet recorded from California. {kvhXo';, rounded; -jtovi, foot.)

2451. LIPAUIS FUCENSIS, Gilbert. 



Head 3i- to Si ; depth 4 to 4.1 . D. V, 30 ; A. 28 or 29 ; C. 18 or 20 ; P. 38 to 

 39. Body moderately elongate, compressed ; head depressed, with gibbous 

 snout and occiput, separated by the depressed interorbital area, which 

 forms a shallow transverse groove. Snout not blunt, the mouth terminal, 

 nearly horizontal, 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 5f in length of head, 1 to l\ times in bony 

 interorbital width, IJ times in snout. Posterior nostril Avithout tube, the 

 anterior with a short tube, less than diameter of pupil. Gill slit com- 

 paratively wide, its width- equaling length of snout and ^ eye, over- 

 lapped by a conspicuous triangular prolongation of the opercle. The slit 

 extends down to opposite the upper third of the pectoral fin. Disk circii- 

 lar, of rather small size, distant from tip of snout 1^ times its own diame- 

 ter, from vent 1^ times. Diameter of disk 2f times in head. Distance 

 from tip of snout to vent 1§ to If in distance from tail. Pectorals extend- 

 ing to a vertical midway between vent and front of anal. Lower rays 

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

 unsegmented, shorter than the succeeding segmented rays, from which 



* The following is the original description of Liparis cyclo]}us: Dorsal 32; anal 30; 

 caudal 12. Caudal fin entirely free from dorsal and anal; the latter commences in the 

 vertical from the seventh dorsal ray; pectoral margin with a notch, some of the lower 

 rays being produced; ventral disk ovate, its length being less than i of that of the 

 head. A tine specimen. Esquimault Harbor. Presented by Lord John Russell. This 

 species agrees in nearly every respect with Liparis vulgaris, from whic)) it difl'ers in the 

 following points besides those mentioned: The greatest depth of the body is nearly | of 

 the total, the length of the head nearly J. The skin is tougher and more firmly adherent 

 to the body. The head is flat above, tlie nape of the neck being scarcely prominent. The 

 nostril is a short tube, situated nearly midway between the eye and the upper lip. The 

 pectoral extends only to the vertical from the' anal papilla, and the dorsal (anal) fin com- 

 mences yet more backward. The teeth are small, with 3 lobes. Infraorbital extending to 

 the predperculum. The color is brownish olive, with darker spots, more conspicuous on 

 the fins than on the body; belly retlclisli. The length of the specimen deacribed is 45 

 lines. (Giiuther.)
