strong- spine at each outer anj^le, directed outwards and backwards; one 

 very small spine between the two last mentioned, directed forwards 

 from the median line. This median spine is not found in any other 

 known species. There are faint, darker (not lighter) bars on back 

 and sides. 



Still a fourth specimen, a female, is in the collection of Stanford 

 University, taken In^ the U. S. Bureau of Fisheries steamer Albatross 

 at station 3259, in Bering Sea, depth -11 fathoms. The head and hodj 

 are veiy much wider than in the specimens noted above, which are 

 all males. The spines are shorter and l)lunter, the eye smaller, the 

 ventrals shorter, and the lower pectoral rays are not produced beyond 

 the outline of the fin. These are all sexual characters, parallel diti'er- 

 ences being found between the sexes in other species. The hn-rays 

 are dorsal V-5, anal 8. 



LIPARIS DENNYI Jordan and Starks. 



Numerous specimens were dredged l)y Professor Kincaid in East 

 Sound, Friday Harbor, and Upright Channel, Washington, in July 

 and August, 1904. 



The species is very close to L.fucensis^ agreeing in size of disk and 

 in the very wide gill-cleft. Z. denny'i is more robust in form, with 

 longer dorsal and anal tins, and these more extensively connate with 

 the caudal tin. The two species form an evident transition to Xeo- 

 I'tparis. In L. dcitnyl the first five to seven dorsal rays are unjointed, 

 slender, and spine-like, but they usually increase in length regularly 

 from the first and can not be distinguished from the articulated rays 

 except by dissection. In the adult type of the species, the first twelve 

 rays are unjointed, indicating apparently that this condition invades 

 the fin with increasing age. Both dorsal and anal join the caudal for 

 almost the entire height of the fins, with little or no notch, the basal 

 third or two-fifths of the caudal being thus adnate with the anal. The 

 dorsal contains in all 38 to 40 rays. 



In L. fticensis the first fi\e dorsal rays are slender and unjointed. 

 They sometimes pass imperceptibly into the rayed portion of the fin, 

 but more often form an anterior lower lobe, separated b}" a shallow 

 notch from the rest of the fin, the middle spines a little higher than 

 the anterior and posterior. Both dorsal and anal terminate in rounded 

 posterior lobes, and are either whollv free from the caudal or join the 

 latter only at its extreme base. The dorsal contains in all 35 or 3») 

 rays. Neoliparis Jissuratus Starks'* is a synonym of L.fucensis. The 

 genus Neoliparls apparently should be withdrawn. 



In the type of L. den in/ i, the diameter of the disk is contained lii 

 times in its distance from tip of mandible, li times in its distance 

 from front of anal. The vent is very slightly nearer the front of the
