534 Mr. H. B. Preston on new 



ovate, having the appearance of being laterally compressed, 

 while in C. mathewsi it is compressed above and laterally 

 dilated. 



Alt. *5, diam. maj. 1*5 mm. 



Hub. Mount Pitt, Norfolk Island (R. Bell). 



CRYPTOCHAROPA, gen. nov. (Endodontidce). 



Shell planulate, incrusted with an agglutinated mass of 

 earth and vegetable matter, whieh broadens out at the peri- 

 phery into a serrated fringe. 



Genotype : G. atlantoididea, Preston. 



The agglutinated covering which is present in every 

 individual seen by the author, and which is extremely hard 

 to remove even after several days of soaking, would seem to 

 be a habitual generic character. The shell has a superficial 

 resemblance to Charopa, though probably having no close 

 relationship with that genus. 



Cryptocharopa atlantoididea, sp. n. 



Shell of moderate size, very depressedly orbicular, almost 

 planulate above, covered with an agglutinated mass of foreign 

 matter which broadens at the periphery into a coarse saw-like 

 fringe or projection, and beneath which the shell is of a 

 reddish-brown colour ; whorls 5, regularly increasing, the 

 last strongly angled at the periphery, sculptured with coarse, 

 irregular, somewhat radiate, transverse, and rather distant, 

 wavy, spiral striae, the latter becoming obsolete on the base 

 of the shell; suture deeply impressed ; umbilicus very wide; 

 columella margin excavatedly angled above, obliquely curved 

 below ; labrum simple, receding below, projecting in front ; 

 aperture subcircular. 



Alt. 1/5, diam. maj. 3*75, diam. min. 3 - 25 mm. 



Aperture : alt. 1*25 (nearly), diam. 1*25 (nearly) mm. 



Hab. Mount Pitt, Norfolk Island (R. Bel/). 



The above measurements were taken after the agglutinated 

 foreign matter had been removed from the shell. 



Paralaoma orestias, sp. n. 



Shell rather small, turbinate, somewhat shining, pale 

 yellowish brown flecked with blotches of white ; whorls 5, 

 the last subangulate at the periphery and descending in 

 front, sculptured, especially on the lower whorls, with arcuate, 

 slightly distant, transverse costula? ; suture impressed ;
