SYSTEMATIC ACCOUNT 57 



216. Eponides karsteni (Reuss) (F 391) (SG 324) (A 503). 

 Three stations: 338, 417, 421. 



Extremely rare : only a single specimen at each station. 

 Pearcey: 447 "rare". 



217. Eponides weddellensis, sp.n. (Plate I, figs. 65-67). 

 Three stations: 286, 417, 421. 



Test minute, biconvex, the dorsal side exhibiting 3-4 convolutions is higher than the 

 ventral and has five chambers in the last convolution ; sutures distinct, flush, their white 

 colour contrasting with the hyaline texture of the chambers ; peripheral edge rounded ; 

 ventral side exhibiting only the five chambers of the last convolution ; sutures depressed ; 

 aperture a minute slit on the inner edge of the final chamber on the ventral side. 



Breadth about o-i6 mm. Height about 0-12 mm. 



Fairly frequent at all three stations, the best specimens at St. 421. The species also 

 occurs at St. 459, outside the convergence, and may have a wide distribution in deep 

 water. Owing to its minute size it would be easily overlooked. 



This little species is probably allied to E. karsteni (Reuss) and closely resembles the 

 small form of that species figured by Brady from Magellan Straits (B. 1884, FC, pi. cv, 

 fig. 8), which is common in many deep-water deposits from the North Atlantic and else- 

 where. But it diff^ers in having an unbroken peripheral edge, and never has the ventral 

 peripheral line shown in the Challenger figure. 



218. Eponides exiguus (Brady) (F 387) (SG 323) (A 504). 

 Five stations: 286, 417, 418, 421, 447. 



Only a single specimen at St. 286, but frequent to common at the remaining stations. 

 Pearcey: 342 "few", 417 "common", 447 "few". 



219. Eponides tumidulus (Brady) (F 366) (SG 312) (A 505). 

 Four stations: 286, 417, 421, 447. 



Rare, except at St. 421, where good specimens were frequent. 



220. Eponides bradyi, Earland (F 367) (SG 313) (A 506). 

 Six stations: 286, 300, 313, 421, 422, 447. 



Common at Sts. 286 and 421 and frequent at St. 447, rare at the remaining stations. 

 The best specimens, i.e. those in best condition, were observed at Sts. 313, 421 and 447, 

 but the majority of the specimens at all stations were dead and often decomposing shells. 



Pearcey records the species under the name TnincatuUna pyguiaea, Hantken, at Sts. 

 300, 342, 420 and 447 "few". 



Genus Laticarinina, Galloway and Wissler, 1927 



221. Laticarinina pauperata (Parker and Jones) (SG 326) (A 509). 

 One station: 417. 



Two large, dead and rather worn, specimens.
