 pi. xxi, figs. 5, 5a. 



Ten specimens, ranging from 18 to 40 mm. in the length of 

 the carapace and rostrum, were found at St. 391. 



In the smaller examples four spines in the median line of 

 the carapace are decidedly longer than in larger individuals, in 

 which they are scarcely distinguishable from the general tuber- 

 culation of the surface. In young specimens also five spines on 

 the lateral margin of the carapace are more conspicuous than 

 in the adult and thus resemble M. miersi, Walker (1890, p. 113, 

 pi. vi, figs. I — 3), though the distinctions between the species 

 still remain quite definite. 



Maia gibba was hitherto known only from the three type 

 specimens obtained in the Andaman Sea.
