LAGENIDAE 113 



supra, p. 413, pi. xix, fig. 3), differing in the absence of a produced neck and the broader 

 and more coarsely tubulated carinae. 

 This species is named after H. F. P. Herdman, M.Sc, of the Discovery staff. 



222. Lagena hexagona (Williamson) (F 202). 



Eight stations: 27, 31, 131 ; WS 27, 33, 42, 154, 522. 



Never very frequent but good and typical specimens, especially at St. 131 and WS 154. 

 The single specimen at WS 522 has exceptionally large and coarse markings. 



223. Lagena hispidula, Cushman (F 180). 

 Four stations: 123; WS 33, 429, 522. 



Single specimens at St. 123, WS 33 and 522. Many smaller but very typical examples 

 at WS 429. 



224. Lagena laevis (Montagu) (F 179). 



Seven stations: 129, 149; WS 37, 50, 66, 429, 521. 



Rare, most of the specimens being small and narrow. At WS 66 a single curious 

 specimen occurred, characterized by a thick glassy shell with a milk-white annulus 

 encircling the test near the base. 



225. Lagena lagenoides (Williamson) (F 226). 

 Two stations: 144; WS 522. 



At St. 144 a single specimen only occurred, agreeing with Williamson's type figures, 

 and one of a large deep-water type at WS 522. 



226. Lagena lagenoides var. tenuistriata, Brady (F 228). 

 Two stations: WS 429, 522. 



A single very fine specimen at each station. 



227. Lagena lineata (Williamson) (F 183). 



Six stations: 123, 144; WS 25, 33, 429, 522. 



Rarely more than a single specimen at a station and all very feebly marked. The usual 

 form is almost globular with a broad oral end, but Williamson's typical oval form also 

 occurs more sparingly. Both varieties are found at WS 33, where the species occurs 

 more frequently than at any other station. 



228. Lagena lucida (Williamson) (F 214). 

 Two stations: 144; WS 33. 



Only a few specimens at each station, the best developed at WS 33. 



229. Lagena lyellii (Seguenza) (F 190). 

 Two stations: 20, 149. 



A single weakly marked specimen at each station.
