Unionidas. 
Unio nanus (Dupuy) and U. amnicus (Retz.) are figured from Savoy speci- 
mens by Bourguignat, Mai. d’Aix, pi. 3. 
M. Bourguignat has figured the following species in Malac. Alg^r. v. : — 
Unio rhomboideus (Moq.-Tand.) (litoralis, Lam.), pi. 18. figs. 1-10, and pi. 19. 
figs. 1-3 j U. durieui (Besh.), pi. 19. figs. 4-8 j U. batavus (Lam., Nilss.), 
pi. 19. figs. 9-11, and pi. 20. figs. 1-4 j U. ravoisieri (Desh.), pi. 20. figs. 5-10 j 
U. moreleti (Desh.), pi. 21, and pi. 22. figs. 1-5 3 U. pictorum (“Philipp- 
son”), pi. 22. figs. 6-11. 
Mr. J. Lea has characterized the following new species in Proc. 'Acad. Nat. 
Sc. Philad. 1864, pp. 285 and 236 : Unio homsensis and U. emesaensis, from 
the River Orontes : U. kidlethensis, U. orpha’ensis, and U. mardinensis, from 
the Tigris or its tributaries. 
Unio megaptems, Morelet, Journ. Conch, p. 159 ; U. mandarinus, Morelet, 
1. c. ; and U. massini, Morelet, 1. c. p. 289 j all three from Cochinchina. 
Mr. Reeve, Conch. Icon., has figured six species which, with the exception 
of the first (which is from Mexico), are North American.” It is possible 
that several of the names designated by Mr. Reeve as manuscript names 
have been published elsewhere, so that such species would not be new for 
the year 1864. The species are the following : Unio corium, Reeve, 39, 
allied to U. pUciferus (Lea) ; U. deviatus (Anthony, MS.), 61 j U. sacculus 
(Anthony, MS.), 67 ; U. nucleopsis (Conrad, MS.), 68 U. mundus (Lea, 
MS.), 72; U. suhrostratus (Say, MS.), 78. 
Unio (Alasrnodon) evansi, Adams and Angas, Proc. Zool. Soc. 1864, p. 39, 
from Lagoon of the Lower Murray Itiver.
