REPOET ON THE BRACHYURA.

Goniosoma variegcitum, var. bimaculcitum, nov. (PI. XY. fig. 3). 
The specimens thus designated come in nearly all of their characters very near 
to the form I regard as the typical Goniosoma variegatum (Fabricius) 1 ( Goniosoma 
callianassa, A. Milne Edwards), which they resemble in the prominent and laterally- 
projecting lateral epibranchial tooth, in the turgid three-spined palms of the chelipedes, 
&c., but are distinguished by having the median and submedian frontal teeth nearly 
wholly coalescent, and forming together a broad lobe with slightly concave anterior 
margin, and in having a very distinct black spot on each branchial region.

Hong Kong, 7 fathoms, from the trawl (a fine adult male). 
In this specimen the frontal teeth are all prominent and well developed ; the first of the 
antero-lateral marginal teeth (or exterior orbital tooth) has a distinctly excavated apex.

Goniosoma ornatum, A. Milne Edwards, Archiv. Mus. Hist. Nat., vol. x. p. 376, 1861. 
Arafura Sea, lat. 8° 56' 0" S., long. 136° 5' 0" E., in 49 fathoms (Station 190). An 
adult ova-bearing and an immature female. 
1 Fabricius’ description of his Portunus variegatus is very brief, and the identification of the species, therefore, 
difficult. H. Milne Edwards, however (Hist. Nat. Crust., vol. i. p. 465, 1834), supposes it to be “ une espece trls-varide ” 
of Goniosoma callianassa (Herbst), and as Fabricius’ name has priority, I adopt it in preference to Herbst’s designation. 
By de Haan (Crust, in v. Siebold, Fauna Japonica, p. 42, pi. i. fig. 2, 1835), Portunus variegatus, Fabricius, and Cancer 
callianassa, Herbst, are regarded as distinct species, but A. Milne Edwards [Archiv. Mus. Hist. Nat., vol. x. p. 382, 1861), 
unites the form figured by de Haan as variegatus with Goniosoma callianassa, although, he uses the last-mentioned name 
for the species. 
2 1 retain Fabricius’ designation cruciferum for this species, although Herbst’s name, cruciatus, has distinct priority, 
because the former is not only the one that has been used by all systematists, but also is clearly indicative of the 
remarkable coloration, in reference to which the term cruciatus is inapplicable.
