Remarks. All the Antarctic specimens have long, numerous, pointed spines on the 

 elytra and unidentate ventral bristles. The examples from the Cape have less sharply 

 pointed elytral spines and bidentate ventral bristles. Willey (1902, p. 267) has created 

 two varieties of this species, a var. acuminata for forms with acuminate elytral spines, 

 such as his specimens from Cape Adare had, and a quite unnecessary var. laciniata for 

 forms with elytral spines resembling those of the type specimen. All my Antarctic 

 specimens belong to Willey's var. acuminata; on the other hand, Bergstrom states that 

 his Antarctic specimens had elytral spines of the var. laciniata kind. 



I am disinclined to attach mucli differential value to variations in the tips of the 

 elytral spines, but I believe that there is a distinct varietal difference between the 

 Antarctic forms and those from the South Temperate Zone, such as Mcintosh's type 

 from off the Crozet Islands and my specimens from the Cape, which have distinctly 

 bidentate ventral bristles. 



I suggest, therefore, that the Antarctic forms with unidentate ventral bristles should 

 take the varietal name applied by Willey to his examples from Cape Adare and be 

 called var. acuminata.

St. 51. 4. V. 26. Off Eddystone Rock, East Falkland Island. From 7 miles N 50° E to 7-6 miles 

 N 63° E of Eddystone Rock. io5-ii5m. Gear OTL. Bottom: fine sand. Two specimens. 



Description. The one complete specimen measures 16 mm. by 3 mm. including the 

 feet. 



The head is not nearly so deeply grooved in front as in the northern form and the 

 palps are proportionately much longer and more slender. The position of the eyes is as 

 in Johnston's species. The median tentacle is lost and the laterals are very small. The 

 tentacles and dorsal cirri are provided with long clavate papillae and the palps with very 

 short truncated ones. An elytron (Fig. 13, fl) from the second pair is all that remains, 

 and this is kidney-shaped, sparsely fringed at the external border with a few small 

 clavate papillae, and dotted all over its surface with small simple tubercles. 



The foot and bristles are very close to those of E. impar. The dorsal (Fig. 13, 6) 

 bristles are numerous and strongly pectinated, and the superior ventral (Fig. 13, f) are
