the Cape Verde Islands, covered by basalt, and already indicated by 
Darwin. The marine species are still living in the neighbouring sea, 
except one {Cerithium amulum ) ; among the land-shells are two extinct 
species. 0. R. 1874, Fob. ; J. de Conch, xxv. pp. 301 & 302. 
Acclimatization. 
A list of 20 species of terrestrial Mollusks acclimatized in foreign 
countries is given by P. Strobel, Atti Soc. Ital. xix. (1876) p. 42. 
acclimatized at Swansea and in Guernsey; R. Rimmer, 
Q. J. Conch. No. 13, pp. 266 & 267. 
Helix terrestris (Chemn.) \elegans^ Drap.] found in North America ; 
Mazyck, P. Ac. Philad. 1876, p. 127. 
Planorhis dilatatus (Gould) acclimatized at Pendleton. Q. J. Conch. 
1877 ; Nachr. mal. Ges. 1877, p. 10. 
Use hy Man. 
Olivella hiplicata, or “ Colcol,” figs. 62 & 63, fragments of Haliotis 
rufescens^ or “ Abalone,” fig. 64, and of PacJiydesma crassatelloides, or 
“ Hawock,” fig. 65, used as shell-money or ornaments by the aborigines 
of North America, described and figured by R. E. C. Stearns, Am. Nat. 
xi. pp. 344-348, pi. ii. (separate). The same author, 1. c. p. 250, gives a 
table of aboriginal shell-money used on the west and east coasts of North 
America, and in the Indo-Pacific and African regions. E. A. Barber, 
tom. cit. pp. 270-272, describes beads cut by aborigines from Oliva 
(hiplicata ?), pi. i. fig. 7, Busy con or Mur ex., fig. 58, Marginella, Fascio- 
laria, and other genera, usually univalves. Stearns, 1. c. pp. 473 & 474, 
refers the Oliva to 0. gracilis or 0. dama^ and states that if it were 
hiplicata, a communication with tribes north of Lower California would 
have to be inferred ; and if the ornaments were from Busycon, a com- 
munication with the Gulf of Mexico would be implied, from the known 
distribution of those shells. 
Dentalium, Haliotis, Olivella hiplicata, and discoidal pieces of Saxi- 
domus aratus, are or were employed as money by the natives in Cali- 
fornia ; L. G. Yates, Am. Nat. xi. pp. 30-32, figs. 2 & 3, and Q. J. 
Conch. No. 11, p. 221. 
Questions of Nomenclature. 
Some observations concerning “species” and “variety”: Sheriff- 
Tye, Q. j. Conch. No. 10, pp. 171-174 ; C. P. Gloyne, 1. c. pp. 175-178.

priority’s sake ; A. Sutor, JB. mal. Ges. iv. pp. 150-156.
