mens were preserved perfccth' in the same solutions which failed to 

 preserve specimens of the latter species. 



As there is some discrepancy between these specimens and the de- 

 scription published by Jordan and Evermann (U. S. Nat. IMus., Bull. 

 47, p. 21 id) the following description is submitted: 



The depth of the body under the anterior dorsal lobe is from 4.2 

 to 4.33 in the length to the caudal base. The length of the head is 

 from 3.50 to 3.66. The maxillary extends to under the anterior margin 

 of the eye; its length is contained three times (or very slightly less) 

 in the head. There are seven or eight series of teeth on each side of 

 the upper jaw counting the series which become parallel with the jaw 

 at the side. Counting the series which run in the opposite direction, 

 or more or less transversely to the jaw, there are fourteen or fifteen. 

 The nostril is in a broad tube ; anterior to it is a large pore, and posterior 

 to it over the front margin of the eye is a larger one. The disk is 

 contained 2.8 in the length of the head, or 1.33 of its own distance from 

 the tip of the jaw. The length of the gill-opening is one-fourth of 

 the length of the head; it extends only very slightly in front of the 

 pectoral, not more than to the base of the second ray from the top. 

 The anal opening is the diameter of the disk behind the disk, and an 

 equal distance from the front of the anal. The longest ray in the 

 lower pectoral base is half the length of the head. The longest pectoral 

 ra>s are equal to the length of the caudal, and are contained 1.66 in 

 the length of the head. The dorsal and anal scarcely join the caudal, 

 or, if at all, only at the extreme base, and there is a decided notch 

 between. The dorsal rays number forty, of which five are of the an- 

 terior lobe, the anal thirty-one, and the pectoral thirty-six. An 

 anterior lobe is separated from the rest of the dorsal fin by a deep 

 notch. 



This species may be known from all other liparids of the west 

 coast having a large anterior dorsal lobe, with the exception of L. 

 viucosus, by the very small gill-opening. L. mucosiis may be at once 

 recognized by the very large ventral disk; the diameter of which is 

 two-thirds the length of the head. 



48. Liparis cyclopus Giinirier. 

 Three small specimens were dredged. The anterior dorsal rays 

 slightly indicate an anterior dorsal lobe, making this one of the inter- 

 mediate forms between the genera Liparis and Xeoliparis.
