Harriman Alaska series . last two segments; the second segment is abouttwice as long as the third. The antennal scale is elongate, about twothirds the length of the carapace; the spine is slender and exceeds theblade. The outer maxillipeds are very slender and extend slightly be-yond the scale. The first pair of feet may not quite reach the scale ormay extend beyond it; the merus has an outer distal spine; the manusis over three times as long as its average width; the immovable digit islong and slender, and the dactylus when flexed is obliquely sternum has a series of median tubercles. The abdomen is smoothly sculptured; there is a blunt median carinaon the third to fifth segments; the first and second segments have atransverse sulcus; the third and fourth segments have each two trans-verse sulci, which are connected either side of the median carina; thesixth segment is furnished with two prominent longitudinal carinse, amedian sulcus, and a sulcus on the outer side of each carina; the seventh. 124 RATHBUN segment has a deep median sulcus. The abdominal sulci are filled witha thin short pubescence easily rubbed off. The sixth segment is aboutone and a third times as long as the fifth. Dimensions.—Female (station 3441), length from tip of rostrum totip of telson 64 mm., length of carapace 16 mm., length of antennalscale mm. Harriman Expedition.—Juneau, 20 fathoms. Distribution. — From Bering Sea to San Diego, California (includingPuget Sound and Strait of Fuca), 20-309 fathoms; taken at 142stations by the Albatross, often in large numbers. Less abundant atsouthern localities. Off southeastern coast of Kamchatka, 96-100fathoms, at two Albatross stations. Two specimens were received from the Hopkins Laboratory at PacificGrove; they were probably taken in deep water. One specimen was collected at Port Etches, Alaska, in 12-18 fathoms,by W. H. Dall. Variations.—-The rostrum in normal individuals does not extend be-yond the eyes; in many cases,
