Starks: Ichihvolocical Survey AiiOUT San Juan Islands. 193 



(lark liar bihiiul, and a narniw, hrokfu bar at I)asc; an olixc-lirown bar 

 extending through the e>c across the cheek; some inconspicuous light 

 brown cross-bars on the body. 



39. Psychrolutes paradoxus Giinther. 

 A few specimens were taken in the seine, but it was not found at 

 all abundantly as was the case at Port Ludlow, Washington, in 1896. 



40. Gilbertidia sigalutes ("Jordan and Starks). 

 A specimen 55 mm. in length was dredged. It is in a much better 

 state of preservation than the type, or the specimen reported upon 

 by Dr. Gilbert (Proc. U. S. Nat. Mas., XXXVIII, p. 981). The 

 specimen at hand dilTers from Dr. Gilbert's specimen (with which it 

 is directly compared) in being much wider, deeper, and with a wider 

 interorbital space, ow'ing wholly to the fact that the latter specimen 

 is greatly shrunken. The skin is lax as in Liparids, and it is covered 

 closely with small papillae. The anterior nostril is in a short tube. 

 The dorsal spines are invisible under the loose skin except at their 

 tips, which extend beyond the skin, appearing as soft tubercles. 

 About half of the length of the ventrals is hidden by the skin. 



Family RHAMPHOCOTTID.E. 

 41. Rhamphocottus richardsoni Giinther. 

 This species was taken rather abundantly by the dredge. It is 

 know-n among the shrimp dredgers of Puget Sound as the "horse- 

 fish." 



Family AGOXID.-E. 



42. Hypsagonus quadricornis (Cuvier and \'alenciennes). 



Taken in abundance at thirty or forty fathoms. These and others 

 from off Washington, collected by the "Albatross," ha^•e the rostral 

 barbel considerably longer and thicker than in some specimens from 

 Behring Sea, with which they have been compared. 



In alcohol there is considerable variation in the markings. Some 

 specimens are slaty-black under the spinous dorsal, the color some- 

 times extending over the belly. In other specimens this region is 

 almost white, and in these the spinous dorsal is also involved. Behind 

 this broad area are sexeral narrow bands variable in width and thick- 

 ness, but more constant in position. There is a dark spot at the base 

 of the caudal, and a dark band follows the posterioroutlineof thecaudal,
