Il8 MOELLENDORFF : LAND SHELLS OF CAROLINE ISLANDS. 



44.— Omphalotpopis angulosa, Ancey. 



Le Natur., 1890, xii, no. 68, p. 11. 

 Hah. — Ponape (Ancey.). 



45.— Omphalotpopis (Stenotropis) laevis (Pease.). 



Realia laevis, Pease, Amer. Journ. Conch., 1865, i, p. 289, ii, t. 5, 

 f. 5. — Pfr., Mon., Pneum. suppl., iii, p. 227. — Omphalo- 

 troijis laevis, Pease, J. de Conchyl., 1869, p. 148. — Kob. 

 et Mlldff., N. Bl., 1898, p. 151. 

 Hah. — Ualan (Pease), Ponape (Pease, Etscheid, Kubary). 

 The name laevis is rather a misnomer, there is vertical and 

 spiral striation. The angulation of the last whorl is sometimes 

 developed into an obtuse keel. The colour, which Pease calls 

 " fusco-cornea," varies a good deal from yellowish-horn colour to 

 reddish brown. I count 5', not 5 whorls, which are not "convexi," 

 but at most " convexiusculi." The preceding species, described by 

 Ancey, is perhaps identical with laevis. 



46.— Omphalotpopis (Stenotropis) tumidula, Mlldff. 



N. Bl., 1S97, p. 168.— Kob. et Mlldff., ibid., 1898, p. 152. 

 Hah. — Naupilo, Ponape (Kubary). 



47.— Gappettia capolinarum (Mlldff.). 



Diadema carolinarum, Mlldff, N. Bl., 1897, p. 168. — Kob. et 

 Mlldff., ibid., 1898, p. 156. 



Hah. — Ponape (Etscheid, Kubary). 



The name Diadema, Pse., cannot stand, being forstalled by Schu- 

 macher 1817 (Crust.), Gray 1825 (Echinod.), Boisd. 1832 (Lepidopt.). 

 Paetel mentions Garreftia, Pease, as a synonym o( Diadema, but I have 

 not been able to find out whether that name was ever published or not. 

 The genus, which was hitherto known from the Society, Harvey, Cook 

 and Viti Islands, has according to Thiele^ a radula of the type of 

 OmpJialotropis and belongs, therefore, to the Realiidae. The Caroline 

 species agrees well with the Polynesian forms in the general outline 

 and the corneous, multispiral operculum with raised ridges. 



47a.— Gappettia eapolinapum sub-sp. pypamis, Mlldff. 

 Diadema carolinarum va.r. pi/ramis, Mlldff., N. Bl., 1897, p. 168. 

 Hah. — Naupilo, Ponape, about 100 m. altitude (Kubary). 

 Higher, 7 whorls instead of 6, the keel of the last whorl more or 

 less evanescent.
