SMITH : CATALOGUE OF GENUS PARTULA. 423 
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 every detail. Nearly all the Partulas in the 
Pease collection were collected by Mr. Garrett, and he gave them pro- 
visional names which Pease generally adopted. As Mr. Garrett retained 
labeled sets of most of the Peasean species, his opinion in doubtful 
cases is of prime importance. ‘This is especially the case since Mr. 
Pease was rather careless in labeling shells and recording localities. 
Many of the habitats attributed to Polynesian shells in his catalogue, 
published in 1871, 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 was 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 was 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 Parfu/a 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 inno other way. Most of the Garrett correspondence was 
preserved. 
Among the Garrett letters there isa MS. catalogue of Partula, un- 
dated, but apparently written about 1881; this appears 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 principal authority for localities in that 
region. Unfortunately the Layard 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.
