The collections described in the following report were made in 

 the islands of Funafuti (Ellice group), Roturna, and Piji 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. Cryptodromia hilgendorfi de Man. 



2. Ebalia erosa (A. M.-Edw.). 



3. Calappa hepatica (Linn.). 



4. Xenocarcinoides rostratus, n. sp. 



5. Menceihius monoceros (Latr.). 



6. Goniocaphyra truncatifrons de Man. 



7. Carupa Iceviuscula Heller. 



8. Neptunns (Achelous) granidatus (H. M.-Edw.). 



9. Thalamita admete (Herbst), var. edwardsi, n. nom. 



10. Thalamita Integra Dana. 



11. Pseudozius inornatusT)a.nsi. 



12. Pseudozius cagstrus (Ad. & Wh.). 



13. Pilumnus prunosus Whitelegge. 



14. Cymo andreossyi (Aud.), var. melanodactylus Dana, 

 lo. Xanihias lamarcTci (II. M.-Edw.).
