164 MR. A. GARRETT ON THE TERRESTRIAL [Feb. 15, 



might, by some, be considered of generic importance. Having only 

 two examples, which appear to be females, I prefer for the present 

 to place the species in the genus Anapera, and to name it 



Anapera fimbriata. 



Smoky yellow, with the abdomen brown ; the epistome pale 

 yellow. The general form and structure are those of A. jxillida, but 

 it is considerably larger. The antennae are beset with long black 

 hairs. There is a thick fringe of long black erect hairs or setae in 

 front of the eye, continued posteriorly along the orbits of the eyes 

 on each side of the middle opaque disk. This fringe exists, but in 

 a much less degree, in A. pallida. The triangle on the vertex is 

 longer than broad, and not transverse as in A. pallida. There is a 

 series of black setae along the posterior margin of the head. The 

 thorax is of the same form and with the same black setas as in A. 

 pallida, but they are stronger and more conspicuous. The rudimen- 

 tary wings are pale smoky yellowish, about as long as broad, with 

 numerous black setae on the costal area. The abdomen is somewhat 

 round, clothed with black hair, which is very short on the disk, long at 

 the sides and apex ; the base has a transverse arcuate fold ; the disk 

 is deeply impressed, but, although this is nearly the same in both 

 examples, it is possibly (he result of contraction. The legs are as in 

 A. pallida, beset with black hairs. 



Length 5 lines. 



7. On the Terrestrial Mollusks of the Viti Islands. — Part I.

The Viti Archipelago, which comprises nearly 200 islands and 

 islets, is embraced in an area between 178° 20' W. and 176° 55' E. 

 long., and between 15° 4/' and 19° 13' S. lat. The islands are dis- 

 posed in three groups — the eastern, intermediate, and western. The 

 former, which is only partially explored, comprises many small islands, 

 mostly of coralline formation, which have been more or less upheaved 

 through volcanic agencies. All the land-shells, so far as known, com- 

 prise the same genera of small shells as obtained in the Tonga and 

 Samoa Islands. The middle portion, which includes all the large 

 islands, though imperfectly explored, have so far yielded many large 

 and interesting species. Besides the same genera which occur in the 

 eastern group, we find the genera Placostylus, Nanina, Diplommatina, 

 Pupina, and Lagocheilus. All these genera, which are represented 

 by peculiar species, connect the land-shell fauna with Australasia 

 and the East Indies. The latest and most interesting discoveiy is 

 the occurrence of the Asiatic genus Lagocheilus, which was found 

 by Mr. Liardet in Gomea Island. The western or Assawa group.
