REPORT OR" THE BRACHYURA.

a. Palms of chelipedes subcristate above, externally hairy. Lateral 
marginal teeth of carapace usually acute in the adult. 
Trapezia cymodoce (Herbst), Miers, 1878 = Trapezia ferruginea, 
Latreille ; Trapezia dentifrons, Latreille ; Trapezia hirtipes, 
Jacquinot and Lucas. Oriental Region. The citations of 
Trapezia cymodoce and dentifrons for this species are a 
little doubtful ; it is certainly the form figured by MM. 
Jacquinot and Lucas as Trapezia hirtipes. 
h. Palms of chelipedes rounded above, externally glabrous. Lateral 
marginal teeth of carapace blunt or almost obsolete in the adult. 
Trapezia ccerulea, Rtippell = Trapezia miniata, Jacquinot and 
Lucas (?) ; Trapezia subclentata, Gersteecker ; Grapsillus 
subinteger, MacLeay. Oriental Region. I was probably 
wrong in designating this species, in 1878, by Latreille’s 
name, Trapezia ferruginea, as that author describes the 
superior margins of the palms of the chelipedes as acute. 
The citations of Trapezia miniata, Trapezia subclentata, 
and Grapsillus subinteger for it, are, on account of the 
insufficiency of the authors’ descriptions, somewhat un- 
certain. 
The following species have a uniformly coloured carapace, and may 
be identical with one or other of the two preceding groups : — 
Trapezia dentata, MacLeay. Cape of Good Hope. (Perhaps 
identical with Trapezia cymodoce.) 
Trapezia fusca, Jacquinot and Lucas. Noukahiva, Marquesas 
Islands. (Perhaps identical with Trapezia ccerulea.) 
Trapezia corallina,, Gerstsecker. Veragua. 
Trapezia nigrofusca, Stimpson. Cape St. Lucas, California. 
(Perhaps identical with Trapezia corallina, but is dark 
brown, not red, and the front is entire, not denticulated.) 
(2) Carapace of a uniform colour, the limbs spotted. 
Trapezia guttata, Rtippell. Red Sea. 
(3) Carapace marked with pink spots. 
Trapezia rufopunctata (Herbst) = Grapsillus maculatus, 
MacLeay; Trapezia tigrina, Eydoux and Souleyet; Trapezia 
acutifrons, A. Milne Edwards, var. Oriental Region.
