LITUOLIDAE 89 



always only half the size of the type" (= H. subglobosus). These specimens were from 

 the Caribbean Sea 530-1830 fathoms. 



Cushman gives a fuller description on the same lines. He says the species is not found 

 on the American coast north of South Carolina. On the European shores of the Atlantic 

 I have found it in many Goldseeker dredgings made in the deeper parts of the North 

 Sea. 



The Discovery specimens are all from deep water, 1536-4845 m., and the stations are 

 spread over the Weddell, Scotia and Bellingshausen Seas. It is always rare, but per- 

 fectly typical four-chambered specimens occurred at Sts. WS 403, 502 and 552. They 

 are usually dark grey in colour. A variety, somewhat larger and constructed of coarse 

 sand with rough exterior, was found with the type at Sts. WS 472 and 502. It agrees in 

 other respects with the type. The number of chambers visible in the last convolution is 

 usually four, but specimens with five chambers have been noted both in the typical 

 smooth form and in the rough variety. The test averages about 0-45 mm. in greatest 

 diameter but ranges up to double this size. 



166. Haplophragmoides subglobosus (G. O. Sars) (F 95) (SG 113). 



Thirty-nine stations: 362, 363, 365, 369, 373, 377, 382-6; 62° 57' S, 60° 20' 30" W; WS 199, 201, 

 203, 204, 377, 400, 403, 468, 469, 471, 472, 474, 479, 485, 495, 498, 502, 503, 505, 506, 507 A, 512, 

 516, 517, 552, 553,555. 



Occurs in the deeper areas of the Bellingshausen, Scotia and Weddell Seas where it is 



often common, even very common at Sts. WS 474, 479, 495 and 502. But with the 



noteworthy exception of the gatherings made in the Palmer Archipelago where it was 



not recorded at all, it is also found in comparatively shallow water, though usually very 



rare, except at St. 363 in the South Sandwich Islands, 329 m., where it was frequent, 



the specimens being constructed of larger sand grains than usual, and rough externally. 



Similar coarsely built specimens were noted at a few other stations, often in company 



with the normally smooth form. In very large individuals the typical single aperture 



becomes a narrow slit, often separated into a series of small apertures extending along 



the inner marginal edge of the terminal chamber. Cushman has separated such 



specimens generically under the name Cribrostomoides bradyi (C. 1910, etc., FNP, 1910, 



p. 108, fig. 167), but I am unable to see any vaHd reason for their separation, even 



varietally, from the type. Every stage in the development of the aperture can be traced 



in gatherings where the species is abundant, as in the Haplophragmium ooze of the Cold 



Area of the Faroe Channel. Specimens answering to Cushman 's figure were noted at 



Sts. WS 495, 502, and doubtless occurred elsewhere. 



167. Haplophragmoides glomeratus (Brady) (SG 114). 



Sixty-two stations: 167, 170, 175, 177, 180, 181, 192, 194-6, 202-4, 206, 209, 360, 377, 383, 384; 

 62° 57' S, 60° 20' 30" W; WS 199, 203-5, 377, 383, 387, 389, 393, 395, 396, 400, 468, 469, 471, 472, 

 474, 480, 482-9, 493, 494A, 496, 498, 502, 503, 506, 507 A, 507B, 509, 512-16, 552. 



Occurs in all the areas, and at all depths between 100 and 4845 m. It is common but 

 small at St. 180 in the Palmer Archipelago, depth 160 m.; common and large at St. 

 WS 472 in the deep water of the Scotia Sea, 3580 m. At Sts. 175, 177, 194, WS 395,
