Bishop Museum specimen is a male. 
Figure I, g, represents the endopodite of the first abdominal 
appendage of a male Gonodactylus guerinu, the explanation of 
which will make plain the main features of the accessory organ 
in this species. There will be seen, in addition to the parts of 
the accessory organ mentioned in the introduction, a_ slightly 
elevated ridge extending across the endopodite between the fixed 
and movable limbs of the forceps and approximately as long as 
the latter. In this species the hooked fixed limb of the forceps is 
very much shorter than the movable one. 
The color of the Bishop Museum specimen, after having 
been preserved in alcohol for five years, is pale brown above with 
the fifth, sixth, and seventh abdominal segments, the antennae, 
attennules, and the raptorial limbs very much lighter in color. 
Both White and Miers mention the marbled color of the 
dried specimen, and Miers adds that it is “light yellowish brown 
varied with darker colour.” According to Brooks the “Challenger” 
specimen, in alcohol, is marked with brown pigment, the carapace 
having a broad, transverse, light band across it. 
The size of the specimen in the Bishop Museum collection 
is 40 mm. from the tip of the rostrum to the extremity of the 
telson, not including the marginal spines of the latter. ‘lhe 
length of the British Museum specimen, as given by White and 
Miers, is 244 inches. The ‘Challenger’ specimen, according to 
Brooks, is 1.12 inches, from the tip of the rostrum to the distal 
extremity of the telson.
