466 Stimpson on the Crustacea and Echinodermata 
tinct from the Telmessus serratus of Wuitr.  Platycorystes 
(Podocanthus) Isenbeckii of Branvt is also properly placed 
in this genus, and I have recently discovered a new species 
in the seas of Northern Japan. 
The reference to LarnEiLLE's work, (Les Crustacés, les 
Arachnides, et les Insectes distribués en familles naturelles, 
Paris, 1825,) for Cheiragonus is given on the authority of 
Branpt. This book I have never seen, but it is said to 
have been republished in Cuvier’s “ Regne Animal”— 
edition of 1829. In this latter publication the name Cheir- 
agonus certainly does not occur, which is singular, and it 
is also remarkable that it should have been entirely over- 
looked by MiuxEe-Epwanps. The name occurs, however, 
in the “ Index Universalis" of Acassrz, and must undoubt- 
edly have been published somewhere by LATREILLE in 1826. 
Whether this author gives a generic character, or a simple 
reference to "T'iLgsius's description ; and whether he desig- 
nates the species as C. hippocarcinoides, I am of course un- 
able to say. If this specific name were not given we must 
call the species C. ambiguus, for 'Tinsrus's reference to 
SrTELLER's MS. name hippocarcinoides is not sufficient to 
give it priority.

GRAPSUS STRIGOSUS. Latreille. 
Grapsus strigosus, LATREILLE. Goniopsis strigosus, De HAAS ; Warre, Brit. 
Mus. Catalogue, Crust. 40. 
Specimens in the British Museum, from Lower Califor- 
nia, are referred to this species by WuiTE. 
GRAPSUS PICTUS. De Saussure. 
Grapsus pictus, De Saussure; Rev. et Mag. de Zoölogie, V. 362. 
This is in all probability not the Grapsus pictus of La- 
TREILLE. It may be either G. ornatus, M. Ep., or ane” 
species ; and is not improbably the same as the preceding. |
