STRUCTURE OP SEVERAL FORIViS OP LAND fLANARlANS. 289 



25. Geoplana lapidicola. — Island of Loo Choo. Stimp- 

 son, 1. c. 



With eyes few in number, scattered on the margins of the head 

 and three or four larger ones on either side on the frontal margin. 

 This will possibly prove allied rather to Rki/ncJiodemus. 



26. Geoplana Tasnianiana. — Tasmania. Darwin, 1. c. This 

 will possibly prove allied to the Australian genus Ccenoplana. 



Genus. — Geobia, Diesing, 1. c. 



Geobia subterranea. — Brazil. Diesing, 1. c, Geoplana svbter- 

 ranea, Pritz Miiller and Max Schultze, 1. c. 



Long and narrow, with rounded extremities, eyeless, and 

 colourless. Lives under ground in the holes of Lumhricus 

 corethnmis, and preys upon that annelid. 



Geitus. — Ccenoplana, gen. nov. Moseley. 



1. Cmnoplana ccerulea. — Parramatta, N.S. Wales, sp. n. 

 Moseley. 



2. Ccenoplana sanguinea. Parramatta, sp. n. Moseley. 



3. Coenoplana snbviridis. — Parramatta. sp. n. Moseley. 



4. Coenoplana ? sp. ? — Ternate Moluccas. Moseley. 



Genus. — Dolichoplana, gen. nov. Moseley. 

 Doliclioplana striata. — Manilla, sp. n. Moseley. 

 Genus. — Uliyncliodemus, Leidy, Proc. Acad. Nat. Sci. Philad., 

 vol. V, 1851. 



1. Rhynchodemus terrestns. — Europe, O. F. Miiller and 

 others. 



2. Rhynchodemns sylvaticus. — N. America, Leidy, 1. c. 



3. RhyncJiodemus bistriatus. — Samoan Islands, Grube. * No- 

 vara, Exp. Zoologischer Theil.,' Bd. ii, " Annehden,'' p. 45. 



4. Rliynchodemus quadristriatus . — Samoan Islands, Grube, 

 1. c. 



5. Rhynchodemns Nietneri. — Ceylon, Humbert, Mem. Soc. 

 Phys. Geneve, 1861, p. 306. 



6. Rhynchodemns Thwaitesii. — Ceylon, Moseley, Phil. Trans. 

 R. Soc, 1874, p. 107. 



7. Rhynchodemns flavus. — Cape of Good Hope. Moseley, I.e. 



8. Rhyncodemus fuscus. Cape of Good Hope. Moseley, 1. c. 



9. Rhynchodemns Tannayi. Brazil. Ferussac, Ann. Gen. Sci. 

 Phys., t. viii, 1821, pp . 90-92, tab. cxvi, 2 et 3. 



It seems probable that this will prove to differ in structure from 

 the Indian and Cape forms. 



10. Rhynchodemus {Geodesmus) bilineatus. Mecznikow, Bull. 

 Acad. St. Petersburg, 1865, vol. ix, p. 433.
