SYKES: ON NON-MARINE SHELLS FROM THE NEW HEBRIDES. 199 
28. AvRIcULUS ELoNGATUS, Parr. 
Hab.—Resolution Bay, Tanna. 
29. Menanta costata, Q. & G. 
Hab.—Havannah Harbour, Efate. 
380. Meranta Asprrans, Hinds. 
Hab.—Havannah Harbour, Efate. 
One specimen is evenly spirally striate all over, not on the lower 
portion of the whorls only, but it is, I think, only a variety. 
31. Menanra FuLGuRANS, Hinds. 
Hab.—Havannah Harbour, Efate. 
32. Metanta Leerer, Brot. 
Hab.—Havannah Harbour, Efate. 
30. MELANTIA, sp. 
Hab.—Renée River, Segond Channel, Espiritu Santo. 
One specimen ; it is allied to If. Lefer, Brot, but the shell is more 
elongate, and the earlier whorls are longitudinally ribbed. Compared 
with UM. fulgurans, Hinds, which it resembles in sculpture, the whorls 
are more inflated and the spirals more marked. 
34. Metanta screro, Gould. 
Hab.—Valua (Banks Is.). 
MM. verruculum, Morel., is a synonym. 
35. TRUNCATELLA vALIDA, Pfeiffer. 
Hab.—Resolution Bay, Tanna. 
Probably this is the same shell as was recorded from the New 
Hebrides by Mons. Mabille under the name of 7. pacifica, Pease. 
36. OstopEs ForNnicatuM (Pfr.). 
Cyclostoma fornicatum, Pfeiffer: Proc. Zool. Soc. London, 1852, p. 146. 
od Recluzianum, Pfeiffer: op. cit., 1853, p. 51. 
Hab.—Port Fila, Efate. 
Var. Maceitirvrayi (Pfr.). 
Cyclotus Macgillivrayt, Pfeiffer: Proc. Zool. Soc. London, 1855, p. 103. 
Hab.—Renée River, Espiritu Santo; Port Fila, Efate. 
These forms are very difficult to deal with satisfactorily, but I have, 
fortunately, had the advantage of examining the original series in the 
British Museum. 0. fornicatum and O. Recluzianum appear to be 
absolutely identical, while O. Macgillivrayi is a larger form, with the 
last whorl more rounded and the spire more produced. I have not, 
however, been able to satisfactorily divide the series, and intermediate 
forms occur. The largest specimens measure over 14 mm. in diameter. 
Kobelt and Moellendorff place O. fornicatum in Lagocheilus and the 
others in Gonatorhaphe, but I think they really belong to Ostodes. 
37. OmpHatorropis varians, Moellendorff ? 
Hab.—Port Fila, Efate. 
The specimens are dead, but from the diagnosis and dimensions 
given I believe them to belong to this unfigured species.
