A FURTHER CONTRIBUTION TO OUR KNOWLEDGE OF THE GENUS 

 CHLORITIS, WITH DESCRIPTIONS OF ELEVEN NEW SPECIES.

PLATE XXI. 



An interesting collection of shells from Australia and the Solomon 

 Islands, sent over by Dr. J. C. Cox, was received by Mr. J. H, 

 Ponsonby on the eve of his departure for an extended tour to the Far 

 East, and has been placed in my hands for examination. This 

 collection contains, besides a number of interesting specimens of 

 known forms, no less than eight new species of Chloritis. A new 

 species of this genus from New Guinea has also been submitted to me 

 for description by Mr. Ponsonby. Moreover, my own collection has 

 contributed two others, both received from the collection of the 

 late Mr. C. E. Beddome ; these were accompanied by labels bearing 

 Mr. Brazier's manuscript names and marked "ex auct." I have 

 adopted these names, as no doubt the shells, so labelled, exist in other 

 collections. At the same time, however, I enter a protest against the 

 bestowal of manuscript names, which gives rise to confusion and is an 

 ill service to science. 



I take this opportunity of referring to the opinion expressed by 

 the late Mr. Ancey^ that Chloritis Malangensis, BuUen, described 

 as from Java,^ is probably identical with Moellendorffia eucharistus, 

 Pilsbry, from Loo Choo. Mr. Eullen has obligingly allowed me to 

 inspect his types of C. Mahmgensis, and on comparing them with 

 Pilsbry's species I find that they are certainly identical. C. Malangensis 

 must therefore be reduced to a synonym of Moellendorffia eucharistus, 

 and, as the locality Java is almost certainly erroneous, this habitat 

 must be deleted. The mistake arose most probably, as already 

 suggested by Mr. Ancey, through Mr. Eouyer, from whom Mr. Bullen's , 

 shells were received. 



Among the shells sent over by Dr. Cox the following call for 

 remark : — 



1 . A sinistral specimen of C. eustoma from the Solomon Islands. 



2. A dead and worn specimen of the very rare C. Beatricis, from 

 British New Guinea. I have seen only one other, which is in the 

 collection of Colonel Beddome. 



3. A large elevated form of C. quercina, measuring: diam. maj. 37, 

 min. 31 ram. ; alt. 33 mm.
