An adult ova-bearing female from Honolulu, 1 8 fathoms, has the spots of the carapace 
and legs much less numerous, the front less deeply incised.

It belongs to the variety which I erroneously referred, in the Report on the Crustacea 
of H.M.S. “Alert” {tom. cit., p. 536), to Trapezia guttata , Riippell. 
Trapezia rufopunctata (Herbst), var. intermedia, nov. (PI. XII. fig. 2). 
Thus are designated a male and two female examples in the collection from Honolulu 
(reefs), which differ from any specimens of Trapezia rufopunctata I have seen in the 
coloration of the palms of the chelipedes, which are transversely marked on the upper 
surface with irregular, reddish lines, which tend to unite and form reticulations ; the 
inferior half of the inner and outer surfaces of the palms are uniformly reddish-brown. 
The body and limbs, except the palms and fingers of the chelipedes, are marked 
with red spots ; the anterior margin of the front is sinuated ; the teeth but very little 
developed ; the median tooth of the lateral margins of the carapace (the lateral epi- 
branchial tooth) blunt or rudimentary ; the anterior margin of the merus of the chelipedes 
is armed with from five to eight serratures, whose margins are crenulated, the palms of 
the chelipedes are compressed, with the superior margins rounded or subacute, but not 
carinated. The ground colour of the carapace and limbs is yellowish, fingers light 
chocolate-brown.
