A description of shells collected and_pre- 
sented to the Museum by Doctor Palmer, 
together with a list of his previous donations 
from the same region. The new genus Hen- 
dersonia (afterwards changed to Henderso- 
niella) is proposed for a remarkable discoid 
urocoptid, and details of its anatomy fur- 
nished by Dr. H. A. Pilsbry are described and 
figured. The following species are figured 
and described as new: Hendersonia palmeri, 
Xanthonyx potosiana, Strepbostyla potosiana, 
S. palmeri, Schazicheila palmeri, and Spherium 
mexicanum. 
Note on the name Hendersonia. 
Proc. Biol. Soc. Wash., XVI, July 12, 1905, 
p. 189. 
The name Hendersonia published in the 
Smithsonian Miscellaneous Collections (Quar- 
terly Issue) being preoccupied by a slightly 
earlier use of the name in Helicinide, the 
new name Hendersonielia is proposed for the 
later genus. 
Note on a variety of Crepidula 
nivea C. B. Adams, from San Pedro, 
California. 
Vautilus, XIX, No. 3, July, 1905, pp. 26, 27. 
A singular race of Crepidula discovered on 
Glottidia albida Hinds, and therefore given 
| 
the mutational name of C. glottidiarum. 
A new proserpinoid land shell from 
Brazil. 
Proc. Biol. Soc. Wash., XV111, Sept. 2, 1905, 
pp. 201, 202. 
The new species, P. derbyi, is described and 
referred to a new section called Staffola. The 
type was presented to the Museum by Dr. H. 
von Ihering and collected by Dr. O. A. Derby 
in Brazil. 
A new chiton from the New Eng- 
land coast. 
Proc. Biol. Soc. Wash., Xvi, Sept. 2, 1905, 
pp. 203, 204. 
The new species, Tonicella blaneyi, is de- 
scribed, from the coast of Maine, collected by 
Mr. Dwight Blaney who presented the type 
to the National Museum. 
Note on the name Hendersonia.

A discussion of Martyn’s life and work, 
with a synopsis of the genera and species con- 
tained in the Universal Conchologist, evi- 
dence being adduced that the first 80 plates

This volume forms a manual of land and 
fresh-water shells of North America north of 
latitude 49° N. Statistics are given with 
geographical tables; the relations with the 
Asiatic, Californian, and Canadian faunas are 
discussed. Thespecies are enumerated under 
a revised nomenclature, many of them are 
illustrated and some new ones described. The 
nomenclature of the genera of fresh-water 
gastropods is revised at length and the groups 
they contain diagnosed. The volume closes 
with a bibliography of works relating to the 
mollusk fauna of the region referred to. The. 
following names are proposed as new: Cyclo- 
limnxa, Lymnxa anticostiana, L. perpolita, L. 
petersi, L. preblei, Paraspira, Pierosoma, Oreo- 
helix stantoni, Planorbis megas, P. rudentis, 
Polygyra megasoma, Planorbula christyi, Tor- 
quis, Succinea alaskana, Valvata pelicoidea, V. 
nylanderi, Vitrina alaskana. 
The types are in the national collection.

The species Calliostoma marionz is described 
as new from the type in the National Mu- 
seum. Itisshown that Eutrochus A. Adams, 
and other names which have been given to 
the umbilicate Calliostomas are, for various 
reasons, unavailable and the name Leiotro- 
chus Conrad, 1863, is resuscitated for them. 
The type is unique.

In revising the Volutide of the Museum,
