Most of the "^^ Albatross'' specimens are more hairy than those described 

 by Henderson. In this respect they agree with M. 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 M. hrevimana 



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. 



Ml 



nitida (A. M. Edw.)t is returned from Paris. It is a male 23 mm. long 

 {'' Blake " Sta. 163, 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 M. ciliata^ are obsolescent.
