The black spots mentioned by Tattersall are distinct, but are decidedly irregular in 
size and distribution. 
The larger of the type specimens measured 28 mm. ; the three examples which 
I have been able to examine are rather smaller.

The types and only other known examples are recorded by Tattersall from coral 
reefs in the G. of Manaar.

In the long description given by de Man I am only able to detect the following 
differences between this species and G. herdmani :— 
1. The carinae of the last abdominal somite are rather narrower and all of them 
terminate posteriorly in spines. 
. The submedian and intermediate teeth of the telson are rather longer and more 
slender, and the inner edges of the former are beset with spinules. 
3. The lateral teeth of the telson are large, well-formed and sharply acute. 
4. The tubercles on the dorsal surface are rather more numerous and each, in place 
of being rounded, is sharply pointed. 
5. The inner uropod has the same form, but is much more strongly bent inwards 
at the apex.

The type specimen was speckled with black chromatophores comparable with 
those of G. herdmant. 
A single specimen, a female 18 mm. in length, is recorded by de Man from Ternate, 
one of the Molucca Islands. No other examples are known.

The telson, which has formed the subject of a longand careful description by Fukuda, 
readily distinguishes G. spinoso-carinatus from all other species of Gonodactylus. In 
brief , the whole surface except for the base of the submedian spines is completely covered 
by nine longitudinal keels. These keels are smooth dorsally, with minute prickles on 
the lateral borders, and a few spinules directed obliquely backwards at their distal ends. 
The median keel is very broad anteriorly. The submedian teeth are large and are 
separated by a deep incision with spinulose margins ; the intermediate and lateral 
teeth are exceedingly small. 
The peduncular segment of the uropods is furnished with three or four spines on 
its dorsal surface in addition to the terminal one. ‘The proximal segment of the exopod 
bears five or six spines on its outer margin ; the first two or three are slender and
