78 DISCOVERY REPORTS 



involute form and an abnormally large form, which is also involute, occur in numbers 

 (e.g. at Sts. 123, 140, 144, 148, WS 25 and 154, MS 68). Abnormal and encysted 

 specimens were seen at several stations, and at St. 149 a specimen of the large form 

 occurred with six young individuals attached. These young shells are apparently 

 megalospheric and consist of three or four chambers. The majority of them lie near the 

 aperture of the parent shell, which from its size (i-2 mm. diameter) is probably micro- 

 spheric. They are presumably a young brood, formed outside the parent shell by the 

 breaking up of its protoplasm into particles surrounding a nucleus, these particular 

 young having remained in contact with the parent instead of achieving freedom. 



A somewhat similar phenomenon of young individuals attached to their presumed 

 parent shell is of fairly frequent occurrence in the Globigerinae and will be noticed under 

 that genus (see p. 120). 



no. Haplophragmoides crassimargo (Norman) (F 92). 

 Two stations: WS 51, 373. 

 Extremely rare. A very good and typical specimen at WS 51. 



111. Haplophragmoides sphaeriloculum, Cushman (F 93). 



Three stations: WS 334, 348, 353. 



Extremely rare, the best specimen at WS 334. 



112. Haplophragmoides scitulum (Brady) (F 94) (Plate III, figs. 11, 12). 



Eight stations: 151 ; WS 48, 50, 63, 63-4, 334, 336, 351. 



Very rare everywhere, the best and most typical specimens at WS 48 and 63-4. At 

 St. 151, WS 63 and 334 the species is represented by an oval variety, with umbiHcal 

 region only slightly depressed. 



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



Ten stations: 151 ; WS 63, 63-4, 334, 336, 351, 353, 429, 521, 522. 



Very rare everywhere except at WS 334 and 521, where the species was frequent. 

 Some excellent specimens at WS 522, rather smaller at WS 63, 63-4 and 521, very small 

 and starved elsewhere. 



1 14. Haplophragmoides glomeratus (Brady). 



Lituola glomerata, Brady, 1878, RRNP, p. 433, pi. xx, fig. i. Haplophragmium glotneratum, 

 Brady, 1884, FC, p. 309, pi. xxxiv, figs. 15-18. 



Haplophragmium glomeratum, Heron-Allen and Earland, 1913, CI, p. 46, pi. ii, fig. 14. 

 Haplophragmoides glomeratum, Cushman, 1918, etc., FAO, 1920, p. 47, pi. ix, fig. 6. 



Three stations: 136; WS 334, 429. 



Very rare everywhere, but quite typical.
