Most of the ‘‘ Albatross” specimens are more hairy than those described 
by Henderson. In this respect they agree with J. ciliata Wood-Mason. 
These specimens also show that the number of lateral spines of the carapace, 
relied upon by Wood-Mason to distinguish his species from JZ. brevimana 
Hend., is inconstant. 
In some specimens there is an extra spine on each side of the front mar- 
gin of the carapace, between the supraantennal spine and the spine at the 
antero-lateral angle. 
Just as these pages are going to press, the type specimen of Munidopsis 
nitida (A. M. Edw.)+ is returned from Paris. It is a male 23 mm. long 
(“ Blake” Sta. 165, Guadaloupe, 769 fathoms), and differs from M. ciliata but 
very slightly. The carapace is less hairy and more polished ; the transverse 
squamiform ridges, which are very evident in JM. cihata, are obsolescent. 
The transverse furrow which divides the terga of the second, third, and 
fourth abdominal somites into two prominent ridges in JZ. ciliata is but faintly 
indicated in J. nitida. The tubercles on the superior face of the merus of 
the ambulatory appendages, moreover, are much less pronounced in Milne 
Edwards's species. In short, JZ nifida is a less heavily sculptured and less 
hairy form than M. ciliata. The characters that separate the two forms 
appear to be of racial or varietal, rather than specific, value, but the name 
M. ciliata may be provisionally retained for the Pacific and Indian Ocean 
form until the distribution of each form is more fully known.
