 Lagena formosa, Millett, 1898, etc., FM, 1901, p. 624, pi. xiv, figs. 10-12. 

 Lagena formosa, Cushman, 1910, etc., FNP, 1913, p. 41, pi- xi, fig. 6. 



Three stations: WS 33, 521, 522. 



A single very fine specimen at WS 33 and 521, and a small one at WS 522. 



215. Lagena formosa, Schwager, var.n. costata (Plate IV, figs. 16-18). 

 One station: WS 522. 



At this station a few specimens of a very distinctive variety were found. The test is 

 rather small and generally presents all the characteristics of the species, but the faces 

 of the shell are ornamented centrally with a few straight costae, four to six in number. 

 These occupy only the centre of the face and do not extend to the raised edge as in the 

 well-known variety comata, Brady. The wing is rather broad and coarsely tubulated and 

 the basal cleft very distinct. 



There is some variation in the relative dimensions of specimens, two of which were 

 respectively 0-35 and 0-40 mm. long and 0-22 and 0-20 mm. broad. 



216. Lagena foveolata, Reuss (F 204). 



Two stations: 126; WS 429. 



Extremely rare. The single specimen found at St. 1 26 is very weak, but at WS 429 two 

 specimens were found which, although very small, are most typical in their markings. 



217. Lagena globosa (Montagu) (F 169). 



Eight stations: 16; WS 25, 32, 33, 66, 314, 521, 523. 



Very rare, seldom more than one or two specimens at each station. The best station is 

 WS 33, where the species occurs typical and large. A compressed variety also occurs 

 with the type at this station and at WS 521. At St. 16 the compressed variety only 

 occurs. 



218. Lagena gracilis, Williamson (F 185). 



Eight stations: 45; WS 37, 45, 47, 113, 429, 521, 522. 



Rare except at WS 37, where a good many typical specimens were obtained. There is 

 the usual wide range of variation in the strength of the markings, which are very feeble at 

 some stations. Those from WS 521 are extremely coarse. At WS 522 there is a series 

 with costae ranging from feeble to very coarse. 



219. Lagena gracillima (Seguenza) (F 177). 



Fourteen stations: 14, 20, 42, 45, 131, 136, 144; WS 33, 37, 42, 50, 154, 349, 357. 



Rare and represented by one or two specimens only at most of the stations. More 

 abundant at St. 131. All the specimens are well developed. Two forms occur, the typical
