PACIFIC SCIENCE, VoL IX, October, 1955 
Sturanya modesta (Pfeiffer, 1853) 
This species was recorded from the Treas- 
ury Group by Smith (1885) and there are 
specimens in the Suter Collection of land 
shells (now in the Dominion Museum), sent 
to Suter by Hedley from the same locality. A 
small yellow helicinid was common in vege- 
tation on Stirling Island but, unfortunately, 
the specimens collected by the writer were 
lost in transit. 
Sturanya solomonensis (Smith, 1885) 
Specimens from Treasury Island were re- 
corded by Smith in his original description 
of the species. Rensch (1936: 682) indicated 
that this species probably was synonymous 
with modesta (Pfr.). 
Geophorus agglutinans (Sowerby, 1843) 
The writer collected a single specimen from 
Stirling Island which is close to, if not iden- 
tical with, this species. There are also similar 
specimens in the Suter Collection (ex Bed- 
dome) from "Treasury Islands.” 
Palaeohelicina egregia (Pfeiffer, 1853) 
Specimens which are referable to this spe- 
cies were collected by N. Gardner from Stir- 
ling Island. 
Pseudocyclotus levis levis (Pfeiffer, 1855) 
N. Gardner collected this species from 
Mono Island. From the Solomon Group it 
has been recorded from Bougainville, Faro, 
Shortland Island, Choiseul, New Georgia, 
Guadalcanar, Santa Anna (Rensch, 1936); 
Nissan (Dell, 1955); and is known to the 
writer from Galera (Suter Collection) and from 
Savo, collected by R. R. Foster. -4-1944. 
Omphalotropis nebulosa Pease, 1872 
This species also was collected from near 
the Seveke River, Mono Island by N. Gard- 
ner. 
Papusuccinea simplex (Pfeiffer, 1854) 
The species was recorded from Treasury by 
Smith (1885). 
Iredale introduced his new genus Papusuc- 
cinea for the New Guinea form, which he 
regarded as distinct from the widespread Suc- 
cinea simplex Pfeiffer originally described from 
"Solomon’s Islands” (not the New Hebrides 
as stated by Iredale), without giving any con- 
crete differences between it and related forms. 
The genus may well be used until anatomical 
investigation determines its validity.

1936 Orpiella treasuryensis (Tryon); I. Rensch 
and B. Rensch, Rev. Suisse de Zool. 43 (32): 
657. 
Originally, this species was described from 
Treasury but does not appear to have been 
collected there since. Rensch (1936: 657) re- 
cords it also from Guadalcanar. 
Genus Dendrotrochus Pilsbry, 1894 
Orthotype: Helix heliconoides, H. &J. { — Helix 
{Geotrochus) cleryi simboana Smith) . 
Baker (1941: 256) has shown that heli- 
conoides (Jacquinot) Pfeiffer must be con- 
sidered to be preoccupied by Mousson. The 
first valid name for this species appears to be 
Helix ( Geotrochus ) cleryi simboana Smith. 
Rensch (1924) has considered a number of the 
species of Dendrotrochus from the Solomons 
and the Bismarck Archipelago to form a 
"Rassenkreis” and has utilized heliconoides as 
the nominate form using cineraceus (H. & J.) 
in a subspecific sense. Helix heliconoides H. &
