to 940 fathoms. Flint gives two Albatrosa stations, D2570 in 1,813 

 fathoms, southeast of Georges Banks and D2760 in 1,010 fathoms, off 

 Bahia, Brazil. 



In my study of the material from the North Pacific it was found 

 to be extremely rare, the two stations of the Cliallenger from off 

 Japan and in the deeper portion of the Pacific being its only records. 



It is plcasureable, therefore, to examine the Albatross material 

 from the Western Atlantic and find that this hitherto comparatively 

 rare species occurs very generallj' and often in considerable numbers. 

 I have made records of its occurrence at 33 stations. There are two 

 forms which may be noted although perhaps not worthy of varietal 

 rank. One is more or less robust with the whole test nearly straight, 

 the other much more slender and the whole test often very irregularly 

 bent. These latter seem to be more characteristic of wp.rmer waters, 

 the depths range from 196 to 2,045 fathoms and bottom temperatures 

 from 36.8° to 51.6° F., the latter being at the shallowest station in the 

 Gulf of Mexico. The species is most common ir_ ir.aterial from 

 Georges Bank southward to Cape Hatteras but occurs in tiij Gulf of 

 Mexico and the Caribbean Sea.
