own conchological collection was especially rich in species from that 

 region ; and it is impossible to read his letters without being impressed 

 by his love for accuracy in ever\- detail. Nearly all the Partulas in the 

 Pease collection were collected by Mr. (larrett, and he gave them pro- 

 visional names which Pease generally adopted. As Mr. (iarrett retained 

 labeled .sets of most of the Peasean sjiecies, his Ojiinion in doubtful 

 ca.ses is of prime importance. This is especially the case since Mr. 

 Pease was rather careless in labeling shells and recording localities. 

 >hiny of the habitats attributed to Polynesian shells in his catalogue, 

 ])ublished in 187 1, are erroneous. Mr. Garrett, on the contrary, was 

 rigidly careful in noting localities ; he kept a daily journal, and was 

 in the habit of noting the discovery of every fresh species of shell, with 

 the provisional name. 



Dr. Hartman's correspondence with Mr. Garrett was carried on dur- 

 ing many years, and was singularly open and friendly. They ex- 

 changed shells constantly, and often sent specimens to each other for 

 comparison. Though both were publishing papers which, to some 

 'extent, dealt with the same subjects, there w^as no shade of the jealousy 

 which is too common in such cases. Each respected the opinions of 

 the other ; each modified his views more or less as he w^as influenced 

 by the other, until they were almost completely in accord. Up to the 

 time of Garrett's death they had disagreed respecting a number of 

 doubtful species; but it is noteworthy that Dr. Hartman's last (MS.) 

 revision of Partula concedes nearly every one of these points. Prob- 

 ably he was right in this ; the naturalist who has collected and ob- 

 served thousands of specimens in the field gains an insight that can be 

 obtained in no other w^ay. Most of the Garrett correspondence was 

 preserved. 



Among the Garrett letters there is a MS. catalogue oi Partnla, un- 

 dated, l)ut apparently written about 1881 ; this a])pears so important 

 that it is published at the end of this paper, together with some extracts 

 of general interest from the letters. 



Mr. E. L. Layard, British Consul in the New Hebrides, and an en- 

 thusiastic conchologist, is the i)rincii)al authority for localities in that 

 region. Unfortunately the Eayard correspondence is incomplete. 

 Many of the letters related in part to the disease (cancer) of which 

 Mr. Layard subsequently died, and for which Dr. Hartman was pre- 

 scribing ; these were destroyed. The remaining letters contain many 

 notes of importance on the New Hebrides Partulas.
