4. Conradia stoliezkiana, n. sp. 



30 Singapore ; coll. Dr. F. Stoliczka. 



Long. 2J, diam. 2J mil. 



Of the usual " turbinate" shape, consisting of four whorls ; the 

 apical two are smooth, the third has two prominent raised spiral 

 keels, coarsely, nodosely reticulated ; the last whorl convexly 

 ventricose, with eight spiral keels, nodosely granulated and with 

 the interstices longitudinally striate ; umbilicus more open 

 than in the Japan species, peristome slightly fimbriate. Dr. 

 Hungerford has dredged a closely allied form at Hongkong. 



5. Conradia adamsiana, n. sp. 



1 Oman, Persian Gulf [type] ; coll. W. T. Blanford, Esq. 

 Long. 1, diam, 1 mil. 



Turbinate, of 3J whorls, the apical ones smooth, the last but 

 one with two raised spiral keels, the last with five. I can detect 

 no longitudinal striation whatever, the interstices consequently 

 appear to be quite smooth ; behind the peristome, which does 

 not appear to be fimbriate, there are two conspicuous, thickened 

 labial " varices"; the umbilicus open, much as in the preceding. 

 Altogether a very distinct though so minate a form ! The Red 

 Sea specimen, which though also in good condition is probably 

 scarcely adult, agrees exactly with the ^type, except in want- 

 ing the characteristic "labial varices" and in that the peris- 

 tome is distinctly fimbriate ; it also shows no signs (under the 

 lens) of any longitudinal or reticulate sculpture. Named 

 in honour of the late Mr. Henry Adams.
