G. brevisquamatus is known to reach a length of 23 mm. It appears to be exceed- 

 ingly scarce and has as yet only been found in the Red Sea.

Gonodactylus fimbriatus is very closely allied to G. brevisquamatus , and appears to be 

 distinguished from it only by the following characters : — 



1. Of the three pairs of longitudinal ridges on the last abdominal somite the sub- 



medians and intermediates are about equal in width, while those of the lateral 

 pair are slightly narrower. 



2. The marginal teeth of the telson are closely similar to those of G. brevisquamatus, 



but the intermediates are rather larger and there are spinules on the inner edge 

 of the latter and on both edges of the submedian teeth. 



3. In the middle of the dorsal surface of the telson there is a large oval prominence 



with a narrower lenticular keel pressed close against it on either side and 



between these, and the thickened lateral margin there are two other feeble 



longitudinal ridges. At the hinder end of the median boss there are three 



small tubercles and two other tubercles, homologous perhaps with those of 



G. chiragra, are found near the anterior margin. All the median dorsal ridges 



stop before reaching the posterior third of the telson, terminating well behind 



the base of the submedian emargination. 



The uropods seem closely similar to those of G. brevisquamatus, but in the ventral 



process of the peduncular segment the inner spine is less than half the length of the 



outer, and is perhaps shorter than in that species. The basal segment of the exopod 



bears no spines on the anterior half of its external margin, but is furnished distally with 



three large recurved teeth. The endopod is flexed outwards and the margins, both of 



this segment and of the distal segment of the exopodite, appear to be fringed with setae 



as in G. brevisquamatus ; their surfaces, however, according to Lenz' s figure, are not 



clothed with hairs. 



Gonodactylus fimbriatus reaches a length of 28 mm. and is recorded from Zanzibar 

 (Lenz) and from Coetivy, Seychelles (Borradaile). 



Since the above was written I have, thanks to the courtesy of the author, had an 

 opportunity of seeing the manuscript of Mr. Patience's valuable account of the Stomato- 

 poda collected by Messrs J.J. Simpson and R. N. Rudmose Brown in the Mergui Archi- 

 pelago and in Ibo Archipelago in Portuguese East Africa. In this paper Mr. Patience 

 gives, under the name G. brevisquamatus, a detailed account and figures of a specimen 

 obtained at Mergui. G. fimbriatus is cited as a synonym and strong reasons for the 

 adoption of this course are adduced. Inasmuch, however, as I have not been able to 

 examine any specimens of this scarce species, I have preferred to let my notes stand in
