them, was the tube dvveller, AncanthogruUa uncinata Stout. Perhaps 

 most common of the dwellers in the kelp from deep water was the 

 species, Nannonyx dissimilis n. sp. of which there were hundreds in 

 one holdfast. Besides the fact of their numbers, these forms were 

 rather conspicuous in the bright orange eggs of the females. Of 

 nearly the same size and also with rather thick bodies was the 

 much less common Ampelisca arUculata n. sp., distinguished by the 

 bright red and black marks on its head. Of the deep water amphi- 

 pods, besides these and tlie two Gammarids previously mentioned, 

 Fimbriella rohusta and Maera simile, there were flve other species. 

 The beautiful Dulichiella spinosa Stoüt, of a delicate green color 

 with red spots, was quite common. Less frequently found was 

 Lemhos concavus n. sp. The little NeopJiotis maequalis n. sp. with its 

 slender arched body, delicate pink coloring, and bright eyes, was 

 occasionally fonnd, as was also Pliotis californica n. sp., and the 

 brown, orange-eyed Erichthoniiis disjunctus n. sp. 



None of the Legion Hyperiidea were recognized. Of the Legion 

 Caprellidea several species were taken from the kelp holdfasts, and 

 a few from Phyllospadix, thoiigh they were nowhere common.

 and triangulär. Eyes large, black, irregulär, sometimes dorsally 

 confluent. Side-plates deep, not serrate, theöth about one half the

Antenna 1 with peduncle stout, first Joint elongate, second and 

 third Short, the second slightly the longer; flagellum 13-jointed, 

 accessory flagellum 8— 9-jointed. Antenna 2 about equal in lengtli 

 to Antenna 1, slender, peduncle longer than the 14-jointed flagellum, 

 penultimate Joint of peduncle longest, antepenultimate slightly shorter 

 than ultimate. Gnathopod 1 long, slendei", and non-chelate. Gnatho- 

 pod 2 long, slender, third Joint elongate, fitth mucli longer than 

 sixth, flfth and sixth densely covered with short setae, sixth small, 

 palm and finger minute. Pereiopods 1—2 slender, second Joint not 

 produced, fourth Joint produced distally behind with seta at apex. 

 Pereiopods 3—5 successively increasing in length, second Joint 

 produced distally behind. Pleopods well developed, biramous, with 

 retinacula. Uropods 1—2 rami subequal, shorter than peduncle. 

 Uropod 3, rami shorter than peduncle, outer ramus two-jointed, 

 .slightly longer than inner, the peduncle with a number of plumose
