THE VOYAGE OE H.M.S. CHALLENGES. 
The remarks appended to the description of the last variety apply with equal or greater 
force to the present, the distribution of which is even more narrowly circumscribed. 
Biloculina striolata has only been noticed in three or four localities, all of them 
amongst the islands on the southern shores of Papua just west of Torres Straits ; namely, 
off Booby Island, 6 fathoms and 8 fathoms ; off Wednesday Island, 8 fathoms ; and 
Flinders Passage, 7 fathoms.

Biloculina comata, Brady, 1881, Quart. Journ. Micr. Set, vol. xxi., N.S., p. 45. 
General characters similar to those of Biloculina ringens or Biloculina bulloides, but 
having a surface ornamentation of close, regular, longitudinal striae. The length of the 
figured specimen is about -^th inch (0'85 mm.), but the species often attains much 
larger dimensions. 
Biloculina comata occurs, in company with other large Miliolce, at depths of from 
300 to 600 fathoms in the North Atlantic and elsewhere. It has been met with at 
five Challenger Stations, in localities very far apart, namely : — off Oulebra Island, 
West Indies, 390 fathoms; north of Madeira, 620 fathoms; on the coast of South 
America, off Pernambuco, 350 fathoms; off Sydney, 420 fathoms; and North of New 
Guinea, 1070 fathoms. It appears also in one or two of the “Porcupine” dredgings 
in the North Atlantic at similar depths.

In selecting a name out of the many that have been devised for the small, attenuated 
or oval variety of Biloculina, it is impossible to pass over that given by d’Orbigny to 
the specimens figured by Soldani in the Testaceographia. Unfortunately the author 
did not choose the most characteristic of Soldani’s drawings of the species, but founded 
his Biloculina elongata on figures which can only be recognised with difficulty, and 
probably for this reason the name has been ignored by most subsequent writers. An 
excellent figure, in front view, is given by Soldani in pi. clvi. fig. v.v. That the Bilocu-
