corded under that name by Spence Bate from Esquimalt, in J. 

 K. Lord's '^Naturalist in Vancouver Island" (from Zoological 

 Record for 1866). It differs, however, from Dana's species in 

 the much shorter lower antennae and deeper coxal plates.

The specimen which we refer with some doubt to this 

 species is a male, about 20 mm. long. The body is propor- 

 tionately narrower (7 mm.) than in Hansen's species. The an- 

 tennae hardly reach beyond the second thoracic segment. The 

 last segment of the abdomen hardly broader than long, more 

 acute than in Hansen's figure and with only 14 spines on the 

 tip.

Description of Female. — The single specimen, measuring 12 

 mm. in length, was taken from the right branchial cavity of its 

 host {linpagiiriis ochotensis (Br.) ), and it is, accordingly, a dex- 

 tral individual i^Bopyrc droit Giard & Bonnier), though the out- 

 line of its body seems at first sight to indicate a sinistral curva- 

 ture, from the concavity of the right margin in the region of 

 the posterior thoracic segments. Closer examination, however, 

 shows that the head and the abdominal region are turned to- 

 wards the left, and that the pleopods of the right side are longer 

 than those of the left, as in a normal dextral individual, so that 

 the peculiar curvature of the body is, in all probability, merely 

 an accidental variation.
