Trichodactylus (Latr.), Sylviocarcinus (M.- Edw.), and DUocarcinus 
(M.-Edw.). The known species are enumerated and characterized by Milne-

f. Naturgesch. xxxv. p. 2. 
Sylviocarcinus panopluSj sp. n.. Martens, 1. c. p. 3, pi. 1. fig. 1, Province Rio

Uca cordata described, with remarks on two other American species, by 
Smith, Transact. Acad. Connecticut, ii. pp. 13-16. [Unfortunately the 
author was not acquainted with Dr. Gerstiicker’s notes on the species of Uca 
published in Troschel’s Arch. f. Naturgeschichte, I860, in which it is shown 
that U. Icevis (M.-Edw.) is the male, and U. una (Latr.) the female of the 
same species.] E. v. Martens remarks that U. una (Latr.) lives in brackish 
water. Archiv f. Naturgeschichte, xxxv. p. 12. 
Ocypode ceratophthalma (Pall. ),/«6r/m (M.-Edw.), and cwc/fwzawo (Latr.), 
from Zanzibar. Hilgendorf, 1. c. pp. 80-82 ; the sound-producing apparatus 
proves to bo a valuable character for specific distinction in this genus as well 
as in Sesar?na‘y that of O.fabricii is figured on pi. 3. fig. 1. 
Gelasimus. Five species from Zanzibar, viz. G. vocans (L.), dussumieri 
(M.-Edw.), Utragonon (Ilerbst), annulipes (Latr.), and chlorophthalmus 
(Latr.), are described by Hilgendorf, 1. c. pp. 83-85, pi. 4. fig. 1 (G. dus- 
sumieri). 
Gelasunus vocator (Ilerbst) —palustris (M.-Edw.), from Rio Janeiro, 
described by Martens, Archiv f. Naturgesch. xxxv. pp. 6-10; it inhabits 
brackish water, and is diflbrent from Sloane’s Cancer qmlustris, which is=G.

gendorf, 1. c. p. 86, pi. 3. fig. 4. 
Eucratopsisy gen. nov. Type Eucrate crassimana (Dana). Differs by the 
sternal position of the verges from Eucrate (De Haan), in which they arise 
from the coxae of the posterior legs, and which therefore belongs to the Car- 
cinoplacidce. Smith, Transact. Acad. Connecticut, ii. p. 36, and Am. Journ, 
of Sci. and Arts, vol. xlviii. p. 391. 
• Grapsus (Geograpsus) ruhidus (Stimps.). Specimens from Zanzibar de-
