44 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL.21 



foraminosa (Thiele), Halichondria sp., Amphilectus fucorum (Esper), 

 and Iophon proximum (Ridley), as determined by Dr. M. Burton, the 

 bryozoan Beanict magellanica (Busk), as determined by Dr. I. Vigeland, 

 and the ascidian Paramolgida gregaria (Lesson), as determined by Dr. 

 W. G. Van Name. 



Depth: Hancock expeditions specimens were dredged in from 5-25 

 fathoms, Lund University Chile Expedition specimens commonly in 

 from 5-45 m, exceptionally in 250-300 m. Specimens from Estrecho de 

 Magallanes, however, were collected intertidally, an example of polar 

 emergence of a mid-latitude deep-water form. 



Breeding: Ovigerous females were collected by Hancock expeditions 

 at Independencia Bay, Peru, on January 14 and February 9-10, and at 

 Viejas Island, Peru, on January 12. The proportion of ovigerous to 

 total females collected was greatest at station 832-38, where 10 of 17 

 females were with ova. This suggests that breeding was well advanced 

 in February, which is Southern Hemisphere summer. Ovigerous females 

 were collected by the Lund University Chile Expedition at Estero 

 Reloncavi on April 1 and in the Golfo de Quetalmahue on May 4, 

 where 100 percent of the females were in berry. 



Remarks: One has only to consult the extensive synonymy above to 

 realize that Eurypodius latreillei has been described and redescribed 

 many times, each author in turn believing that the specimen or speci- 

 mens before him represented something unique among Crustacea, whereas 

 all were but differing manifestations of a highly variable organism. Milne 

 Edwards and Lucas (1843) and A. Milne Edwards (1891) each recog- 

 nized two species, the second being E. audouini. Dana (1851a, 1852) 

 and Targioni-Tozzetti (1877) each recognized three species, the former 

 describing E. brevipes and E. septentrionalis in addition to the parent 

 species, the latter proposing E. danae while according separate treatment 

 to E. audouini and E. latreillei. Cunningham (1871) carried this trend 

 to the ultimate in recognizing four species, although himself describing 

 none. It was Miers (1881), followed by Ortmann (1893), who initiated 

 the present trend in synonymy by considering all specimens then in the 

 British Museum as representing a single species, although even he could 

 not refrain from designating two varieties of the male, a and /?, which 

 designations, further perpetuated by Coutiere (1900), are repeated above 

 because of their historical interest. (See Description, above) 



A neo-Milne Edwardsian tendency to return to two named forms 

 is apparent in the recent designation of a form closely resembling 

 Eurypodius audouini as E. quiriquinensis Yanez. While the writer agrees
