Lanzarote, 30 on Fuerteventura, 43 on Grand Canary, 90 on 
Teneriffe, 24 on Gomera, 43 on Palma, 17 on Hierro, and of 6 
the particular localities are not yet known; 177 are certainly 
still living, the rest appearing to be extinct (subfossil) ; 16 
species only are European. The subgenera and genera prevail- 
ing in the Canaries coincide somewhat more with those of Spain 
than of Madeira and Porto Santo ; and the subgenus Hemicycla^ 
Monilearia, and several species of Gonostoma with a simple peri- 
stome among the Helicida, the group Napa^us among the Bulimia 
and the entire w ant of the genera Clausilia, Succinea, and Limruea 
appear the most characteristic features of the fauna. The 0 
plates of this work arc also published in Pfeiffer’s 'Novitates 
Conchologicse,’ iv. parts 40-43, as plates 119, 120, 122-124, 
with the same numbers of figures. 
St. Helena. 15 species of land-sliells found by J. 0. Melliss on this island 
are enumerated by J. G. .Jeffreys, Ann. N. II. (4) x. p. 2(34; 8 of these ap- 
pear to be peculiar to the island, 6 are European, 2 not specifically determined, 
and 5 others, apparently also peculiar, have been described by former authors 
from the same island. Martens, Nadir, mal. Ges. 1872, pp. 68 & 69. 
Madagascar. 2 new freshwater shells described by Crosse and Fischer, 
J. de Conch, xx. pp. 200 Sz, 210. 
5. East Indies. 
Hanley and Theobald’s ^ Conchologia Indica ’ (1870) is a col- 
lection of figures of land and freshwater shells from British India, 
just in the same manner as those in Reeve’s ^Conchologia 
Iconica,’ and often apparently copied from that work, and there- 
fore useful enough for the determination of such shells ; but the 
letterpress is even poorer and less satisfactory than that of 
Reeve, no descriptions being given, but onlj^ the name, some 
quotations, and localities. Each plate contains mostly shells of 
the same genus ; but beyond this there is no systematic arrange- 
ment (even Nanina is not separated from HelLv) . The 3 parts 
seen by the Recorder contain 60 plates and 28 pp., and treat of 
the following genera ; — Gyclopliorus, pis. 1-4, 33, 34, 47, 48 ; 
Leptopoma, 6 ; Aulopoma, 4 and 47 ; CyclotuSy 4 ; Pterocyclus 
(including Spiraculum and Bhiostoma) , 5 and 49; Otopoma, 6 ; 
Megalomastoma^ 7 ; Lagochilus, 6 ; Pupina, 7 ; PoinatiaSy 7 ; 
Helicina, 6 ; Bythinia, 37 & 38 ; Stenothyra, 37 ; Boysia and 
Hypselostonia, S ; Streptaxis, 8; Helix, 13-16, 25-32, 50-60; 
Bulimus, 19-23; Achaiina, section Electra, 17, 18, 35, 36; 
Spiraxis, 19; Clausilia, 24; Unio, 9-12, 41-46; IVigonodon 
and Pseudodon, 9 ; Spatha [?] , 9. Several species already de- 
scribed by Benson and others appear to be figured for the first 
time in this work.
