BORRADAILE, M.A., F.Z.S., Lecturer in Natural Sciences of Selwyn College, Cambridge. [Received March 31, 1900.] (Flates XL.-XLII.) The collections described in the following report were made in the islands of Funafuti (Ellice group), Botuma, and Fiji by Mr. J. Stanley Gardiner, to whose kindness I am indebted for permission to examine them. They contain altogether examples of 77 species, of which seven appear to be new to science. All the known species have been already recorded from the Indo-Pacific region, and the new ones present no particularly remarkable features, although it has proved impossible to place one of them in any known genus, and a new division of that rank has been established for it. The Funafuti collection contained examples of the following species:- 1. Crgptodromia hilgendorfi de Man. 2. Ebalia erosa (A. M.-Edw.). 3. Calappa hepatica (Linn.). 4. Xenocarcinoides rostratus, n. sp. 5. Meiicethius monoceros (Latr.). 6. Goniocaphyra truncatifrons de Man. 7. Carupa Iceviuscula Heller. 8. Neptunus (Achelous) granulatus (H. M.-Edw.). 9. Thalamita aclmete (Herbst), var. edwarchi, n. nom. 10. Thalamita integra Dana. 11. Pseudozius inornatus Dana. 12. Pseudozius caystrus (Ad. & Wh.). 13. Pilumnus prunosus Whitelegge. 14. Cymo andreossyi (Aud.), var. melanodactylus Dana. 15. Xanthias lamarcki (H. M.-Edw.). |
