MOLLUSCA FROM EIGHT HUXDRED FATHOMS — HEDLEV. 361 



CartcfJIaria micrn, Tate/' in the Tate Collection, University 

 Museum, Adelaide. The fossil has more and finer spirals, but 

 weaker radials. Tn size, shape, and otlier respects they are 

 identical. My conclusion is that the recent C. scobiiKi may be 

 reiifarded as a sliifht variation of the fossil C. viicra. 



Philine oscitans, S/J. ?iOtv 



(Plate Ixvii., fig. 17). 



Shell small, opaque, moderately solid, oblong-ovate. 8pii-e not 

 concealed, plane, of two and a half i-apidly increasing whorls, 

 separated by a deep sutural furrow. Sculptured by spiral rows of 

 small close punctures, radially undulate with rather coarse incre- 

 mental lines. Colour, pale yellow. Aperture very large, rounded 

 anteriorly. Columella witli a heavy callus. Outer lip free at the 

 vertex, ending in an acute angle. Length, 2, breadth, I'G mm. 



A single specimen from 800 fathoms. On reconsidering the 

 species noticed (ante p. 288) as P. trappzia from 80 fathoms ofl:' 

 Narrabeen, I find that these specimens belong to the present foi'm. 

 Philine trapezia, Hedley,'' is related but is narrower, thin, and 

 possessess a distinct and characteristic angle. 



Led A PALA, sj>. jior. 



(Plate Ixvi., fig. 1). 



Shell small, smooth, inequilateral, moderately inflated, tlie 

 rostrum not differentiated from the remainder of the valve, with 

 a slight pearly sheen. Culour, olive-buff. Umbo prominent, 

 antei'ior and ventral margins rounded, posterior dorsal margin 

 concave. Hinge with 10 posterior and 8 anterior teeth. Specimen 

 drawn is — height, 2-85, length, 4-25 ; depth of single valve 1"15 

 mm. Another fractured valve is 4"1 mm. high. 



Numerous separate valves from 800 fathoms. 



The novelty approaches J^eda oblomja, Pelseneer,""' from the 

 Antarctic, but is less pointed posteriorly.
