LAGENIDAE 115 



One station: WS 522. 



A single specimen 0-20 mm. in width occurred, differing from Sidebottom's figure 

 only in the absence of the few basal spines and the lesser development of the principal 

 carina. It may be observed that no mention of these spines is made in the text, although 

 they are presumably responsible for the assignment of the form to L. staphyUearia. But 

 they appear to bear no relationship to the marginal spines of that species, and both 

 Sidebottom's figure and my own specimen would appear to be more nearly related to 

 L. margiiiata. 



234. Lagena marginata var. striolata, Sidebottom. 



Lagena marginata var. striolata, Sidebottom, 1912, etc., LSP, 1912, p. 408, pi. 18, figs. 10, 11. 



One station: WS 522. 



Two specimens only were found. They resemble the finely striate specimen (fig. 10) 

 figured by Sidebottom, but the markings are much more delicate. Though very distinct 

 over the base and edges of the flask, they become indistinct over the central and upper 

 half, appearing more as hair-streaks than as definite striae. There is no basal cleft as in 

 Sidebottom's figure, the carina being continuous round the base. 



235. Lagena melo (d'Orbigny) (F 200). 

 One station: WS 33. 



A single, rather weak specimen at WS 33. 



236. Lagena orbignyana (Seguenza) (F 240). 



Five stations: 15; WS 33, 37, 42, 314. 



Never more than a few specimens at a station, very good and typical specimens of the 

 nearly circular form at WS 33 and 314. At WS 37 and 42 a small variety occurs with the 

 central carina abnormally developed in the basal half and all three carinae partly sup- 

 pressed in the oral half of the shell. 



237. Lagena quadralata, Brady (F 230). 



Two stations: 136; WS 33. 



A single specimen at St. 136 and four at WS 33. They are all fine examples of the 

 many-winged form described by us from the Falkland area. 



238. Lagena quadrata (Williamson) (F 218). 

 One station: WS 521. 



A single good specimen. 



239. Lagena reticulata (Macgillivray) (F 199). 

 One station: WS 25. 



A single good specimen.
