342 ME. G. BtTSK ON THE SPECIES OF CELLEPOEA 



2. The South-Atlantic furnished five, from depths varying from 

 5 to 600 fms. 



3. The Kerguelen or South-Indian region yielded seven, all 

 from the immediate neighbourhood of Kerguelen's Land, and 

 from depths varying from 20 to 150 fms. 



4. The Australian region afforded eleven species, all, with one 

 exception (0. solida), from depths varying from 2 to probably 

 not more than 40 fms. The exception is a very aberrant form, 

 and only doubtfully referred to the genus ; it was procured from 

 a depth of 2600 fms. 



5. The North-Pacific region furnished only two species, one at 

 18 and the other from 310 fms. ; and 



6. The South-Pacific three or four species, from depths varying 

 from 45 to 150 fms., except in one rather curious instance, in which 

 the specimen appears to have been brought up from 1325 fms., 

 near the western coast of South America. The circumstance is 

 curious, since the same species, O. Eatonensis (var. magellensis), 

 occurred near the Falkland Islands at a depth of not more than 

 5 to 12 fms. 



On the whole, the genus, as represented in the present collec- 

 tion, would appear to belong to comparatively shallow water.
