Caprella tuberculata. 



Inner antenmi? long with a fringe of long seta' on their underside; second, 

 third and fourth joints about equal in lensth. Outer antenna 3 without seta?, 

 almost as long again as inner ones: flagellum somewhat larger than the two 

 last basal joints; second basal joint larger than the preceding or succeeding 

 ones; the entire base not quite as long as inner antenna?. 



Propodus of 1st and 2d pairs oblong ovate, without teeth or spines, dactylos 

 long and slender, fitting close to palmar surface. Manus of second pair spin- 

 ose at extremity. Branchia? short and thick. 



2d, 3d, 4th and 5th segments long, sub-equal, the 1st segment somewhat 

 shorter, the 6th and 7th very short. The whole of the dorsal surface sparsely 

 covered with small sub-spinose tubercles. 



Length of a large female, 0.90; ditto, from extremity of larger antenna? to 

 top of posterior dactyli, 1.75; of outer antenna?, 0.56; of inner, 0.30 in. 



Several specimens, chiefly females, were brought from Icy Cape by Mr. W. 

 J. Fisher, who procured them by dredging, at a depth of from seven to fifteen 

 fathoms. 



Megalor chest in. franmscana . 



Body smooth; superior antenna? one-third longer than the body, the flagel- 

 lum longer than the base, with about thirty-five oblong joints. Superior an- 

 tenna? reaching to middle of 2d joint of inferior. Second epimerals longer 

 than deep, fifth short, bi-lobed. Anterior feet unguienlate, joints scabrous. 

 Hand of second pair very large, oblong ovate, with an almost transverse 

 palm, having a low oblong tooth near centre of palm. Dactylus much curved, 

 touching palm at point only when closed. 



Length of body, 0.87; of inferior antenna?, 1.15 inch. 



A single specimen of this species was found by myself among the debris at 

 high-tide level, Alameda Co., Cal. 



The antenna? in the recent specimen were red. 



This amphipod resembles 0. scabripes, Dana, but differs /from the figure of  

 that species in Dana's work in the greater number of joints of the inferior an- 

 tenna?, the shape of the tooth of the hand, and the proportion of the second 

 epimerals. From M. Californiana, Brandt, it differs in the short fifth epim- 

 eral, and the scabrosity of the feet. 



(Edicerus Behringiensis. 



Cephalic shield rostrate, the rostrum about one-third the length of superior 

 antenna?, curved downward, pointed. Eyes moderately large, contiguous. 

 First six thoracic segments much shorter, with a slightly raised keel in the 

 centre of each. Seventh and abdominal segments long, the seventh thoracic 

 and two first abdominal with the carina divided into two sub-equal teeth, the 

 third abdominal with a long low carina ending in a spine posteriorly. 



Fourth epimeral much longer than the fifth. Superior antenna- about * 

 three-fourths the length of the inferior; flagellum twice the length of last basal 

 joint. Inferior antenna? about one-third as long as the body, proportions like 

 those of superior. Hands of first two pairs of feet oblong ovate, palms nearly
