MTBIOPODA OF THE MEBGTJI AECHIPELAGO.

of the upper extremity of this series. In one female specimen 

 the left eye consists of sixteen ocelli, nine being arranged in a 

 linear series, with three on the inside and four on the outside of 

 the series. This abnormal arrangement calls to mind the aggre- 

 gate eye of the Sphaerotheria. 



Posterior dorsal plate of different individuals exhibiting dif- 

 ferent degrees of emargination. 



In the male the coxse of the eighteenth pair of feet are not 

 coalesced, and these limbs are relatively larger when compared 

 with the copulatory feet and with the preceding pairs, than they 

 are in, e. g., G. connexa. 



Copulatory feet very stout, composed of five segments ; inter- 

 coxal lamina pyriform, with short and slender lateral processes ; 

 second segment towards its distal end giving off inwardly a seti- 

 ferous process ; third segment bearing two processes, an anterior 

 and a posterior — the former short, conical, setiferous, the latter 

 broad and somewhat quadrate ; fourth segment bearing an 

 upturned tooth; fifth segment curved. 



Xine specimens, five males and four females, preserved in 

 spirit of wine. From Elphinstone Island. 



This variety differs from the typical form in the absence of the 

 red colouring-matter on the segments. 



The occurrence of this genus in the Oriental Region is of 

 peculiar interest, since its headquarters appear to be the Medi- 

 terranean district of the Palaearctic Region. In the Ethiopian, 

 Oriental, and Australian Regions its place is taken by the allied 

 genera SjpTicErotJierium and Zeplironia. 



In 1S65, however, Dr. Wood (Proc. Acad. Xat. Sci. Philad. 

 p. 172) described a species of Glomeris from Hong Kong. To 

 this he gave the name bicolor ; but his description of it is so 

 inadequate, that I am unable to say whether or not it is identical 

 with this species from Tenasserim and AEergui. So far as may be 

 judged by the description, it appears to apply to a different form.
