Dr. Faxon's specimens were from Albatross stations 3353, in 095 

 fathoms; 3363, in 978 fathoms; 339;^, in 1,270 fathoms; 3393, in 1.020 

 fathoms. Five specimens at the four stations. 



Professor Henderson's specimens were from Challenger stations 191 

 oli' the Arrou islands, in 800 fathouLs. and 218 between Papua and the 

 Admiralty islands, in l.o70 fathoms. 



The Indian Museum specimen was taken in the Bay of Beng-al, in 

 1.310 fathoms. 



Professor Henderson's iigures 1 and 2 in the CliaUenger report 

 probabl}^ represent two distinct species; not only the nnich smoother 

 carapace and lack of prominent lateral spines in the young foiin 

 shown in tig. 2, but the lemarkable difference in the line of the front 

 from the antero-lateral angle to the end of the rostrum, if the figures 

 are correct, marks a difference not due to age. This is all the more 

 likely, as the form shown in ffg, 2 was taken at a distance from the 

 form shown in fig. 1. 



Mdtildopsls nltida A. Alilne- Edwards, from the West India region, 

 as has been pointed out by Dr. Faxon, is a closely related species; 

 six specimens in this musiHim from station 2110 off Jamaica show a 

 great range in size; five are under 6 nun. in length, and one is 21 nun., 

 measured from the tip of the rostrum to the posterior margin of the 

 carapace; in all, the lines of the front are much like J/ ciliatif, as 

 shown in Professor Henderson's fig. 1, while the carapace is nmch 

 more like fig. 2.
