THE VOYAGE OF H.M.S. CHALLENGER. 
remark that in some localities a majority of the specimens never pass beyond the 
Glandulina - like stage. 
Nodosaria comata has been obtained somewhat plentifully off Bermuda, 435 fathoms ; 
and more sparingly off Culebra Island, West Indies, 390 fathoms ; off Sombrero Island, 
West Indies, 450 fathoms.; and in harbour-mud from Port Louis, Mauritius. It has been 
found also in the Adriatic. 
Jones and Parker record its occurrence in the Subapennine Tertiaries of Italy.

J udged by typical specimens, this is a well differentiated species. The test is straight ; 
the segments comparatively few, generally from three to six in the adult shell and never 
more than eight, inflated or subglobular, and increasing rapidly, though not always 
regularly, in size. The final chamber is drawn out into an apertural tube of some 
length with a terminal phialine lip, and the opposite extremity of the test is commonly 
mucronate. The superficial costae vary both as to number and thickness, and are frequently 
more numerous and less strongly marked than shown- by the figures. The range of varia- 
tion in this and other particulars is very fully illustrated in the beautiful series of 
drawings given by Silvestri, under the name Nodosaria longicauda (loc. cit.). It is need- 
ful to remember that the present form is not the Nodosaria scalaris of d’Orbigny’s 
“ Tableau Methodique.” 
At one or two localities the species exhibits a tendency to assume the peculiar habit of 
growth represented in Pl. LXIY. figs. 16-19. An apparently complete shell of three or
