MObLUSCA FROM EKMIT IIUNURED FATHOMS — IIKDLEY. 357 

 LlOTIA CAPITATA, sj>. uov. 



(Plate Ixvii., figs. 13, U). 



Shell iniuute, subdiscoidal, spire slightly elev'ate, umbilicus wide. 

 Colour cream. Whorls three. Protoconch of a whorl and a half, 

 tilted and inflated. Last whorl scarcely in contact with its pre- 

 decessor, at last deeply descending. Sculpture, sliarp projecting 

 ring ribs, widely spaced on the last half whorl, but crowded on 

 the penultimate, the interspaces and protoconch smooth. 

 Aperture oval, oblicpie, entire, downwardly directed, fortified by 

 a prominent ring varix. Height 0-6, major diam. 1'3, minor diam, 

 0-9 mm. 



A single specimen. 



The present is closely related to liiffoiifia pemambucfusis," 

 with which the apex especially associates it, but from which it 

 differs by being about half the size and not involute. Though 

 these are not typical Llofla, that genus seems to harmonise better 

 with their appearance than does Bifronfia. 



TuRnrn-XLA curialis, sp. nm\ 



(Plate Ixvii., fig. 19). 



Shell veiy small, turrited. Colour pale cieam. Whorls eleven 

 including a protoconch of two rounded whorls. Sculpture, the 

 third, fourth, and fifth whorls have a single smooth spiral rib 

 running between the centre of the whorl and the lower suture. 

 From the sixth whorl onwai'ds, this spiral develops conspicuous 

 grains, about fifteen to a whorl, but finally these become olxsolete 

 behind the aperture. F'roiu the .seventh to the last whorl two 

 narrow, wide spacefl smooth spiral lyrae re\'olve above the bead 

 row. Five low spirals ornament the base. Aperture defective in 

 all examples seen, but the direction of growth lines indicate a deep 

 median sinus. Length, 7, breadth 2 •95 mm. 



Several specimens from SOO fathoms. 



Tn size and shape this n^sembles T.cnniiiJata, Donald,'' but differs 

 in the spiral sculpture.
