BARBADOS-ANTIGUA REPORTS oF 
came available for examination. It seems that this will be the case, for 
here we have a very distinct variety of what is specifically, unmistakable 
Gonodactylus oerstedit. 
As in variety H, affinis de Man22 segregatus Lanchester2?3) of G. 
chiragra, at the hinder end of the median keel of the telson of G. 
oerstedu var. spinulosus, there is present on either side, a smaller ridge 
almost or quite independent of the middle keel, and armed, each with two 
little tuberculiform spinules; one such spinule terminates the median 
carina posteriorly. Half way between the apex of the V of the median 
notch of the telson and the end of the swelling carrying the median 
carina, there is a small semicircular swelling, with convexity directed 
backward, which is often armed with four likewise tuberculiform spinules, 
one either side of the mid-point, and usually a second external to each of 
these. The bases, or anterior ends of the carine which terminate in the 
sub-median points of the telson, are broadened out proximally or swollen, 
in order to carry two small accessory or minor ridges, one either side of 
the carina proper, and armed each with a single spine at the middle, or 
as is sometimes the case, at the proximal end; the median of these three 
carine, or the carina proper, is armed in that portion between the minor 
ridges of the base with three or four spinules in a longitudinal row. 
Furthermore, the little lobe situated at the apex of the notch between 
the submedian, and the intermediate or first lateral teeth or points of 
the telson of the typical species, in this variety is spiniform, and more- 
over on the little ridge or keel with which it is provided, carries a second 
little spinule justi above the terminal one; often too, the posterior margin 
of the telson carries a second spinule just external to the one just men- 
tioned, about in line with the two or three teeth usually carried by the 
supplementary carina, which distinguishes the species from its Pacific 
relative—G. chiragra—in effect making the supplementary carina appear 
to be armed with an extra, third or fourth tooth. The submedian, or 
intermediate carine, either side of the median keel—not the accessory or 
minor ridges mentioned above—end in a sharp spine, as in the variety 
curacaoensis, and often as in the type behind and below this on the 
swelling which carries the carina, there is a second spine or spiniform 
tubercle in line with the first. 
On the middle back of the first and fourth abdominal somites of most 
of the specimens are paired black markings, squarish designs looking 
much like some of the Chinese ideographs; in one of the two specimens 
in which they are not discernible they have partly faded; in none of the 
typical oerstedu did I find such markings.
