the margins all round with longer plumose setae. The ventral surface is 

 smooth. 



The dorsal surface of the endopod is smooth but the ventral surface is 

 clothed with short plumose setae, with a bunch of longer setae on the proximal 

 part, while the margins are armed all round. 



The present specimens show the closest resemblance to Paulson's figures, 

 and the main differences are in minor points which may quite reasonably 

 have been overlooked by Paulson in his specimens. These differences are 

 (f) the presence of spinules on the margins of the teeth of the telson, (2) the 

 presence of a faint carina lateral to the submedian carinae of the telson, 

 (3) the presence of two tubercles near the anterior margin of the telson, one 

 on each side of the median elevation, and (4) the special and peculiar 

 armature of setse on the uropods. 



With the exception of the last character, which is likewise not noted by 

 Lenz, these differences bring Q. brevisquamatus into closer agreement with 

 G. fimbriatus, Lenz. The most serious differences between my specimens 

 and G. fimbriatus are : — 



(1) The form and size of the carinas of the sixth abdominal segment. 



Lenz figures the submedians and intermediates as more or less equal 

 in size, whereas in my specimens the submedians are distinctly wider 

 than the intermediates. 



(2) The presence of two carinae on each side of the submedian earinae of 



the telson. 



Minor differences may also be noted in the different shape of the outer 

 spine of the ventral prolongation of the uropod, in the larger size of the 

 intermediate teeth of the telson, and in the absence of the short straight 

 spines proximal to the strong recurved spines on the outer margin of the 

 exopod of the uropods. 



I do not think that any great weight is to be attached to these differences. 

 Some are no doubt due to age or to individual variation. Borradaile, it is 

 true, identifies specimens from the Seychelles with G. fimbriatus without 

 comment, but the examination of these specimens from the Red Sea, 

 undoubtedly G. brevisquamatus, Paulson, has served to lessen the gap 

 between this species and G. fimbriatus, and I feel no doubt as to the correct- 

 ness of Mr. Patience's conclusion that they are synonymous. 



G. brevisquamatus has been recorded from the Red Sea by Paulson and 

 Nobili, and as G. fimbriatus from Zanzibar (Lenz) and the Seychelles 

 (Borradaile).
