(USNM) ideulified by Wilson as C. armata was carried out. Almost all 

 of ^Yilson's determinations proved to be erroneous; C. armata was not 

 present at any of the Carnegie stations and onty at Albafrosfi station 

 2195 (lat. :J9°4-i' N., long. 70°03' W., off Cape Hatteras). 



C. aethiopica Dana, a widespread species in temperate and tropical 

 waters of all the oceans, was not found in either the Alaska or Gill 

 collections. It will probably be found at least in the region covered 

 by the Gill, since it has been reported from the Bermuda area (Moore, 

 1949), and Mr. Philip St. John (personal communication) has found 

 it in plankton hauls made otT the coast of North Carolina. 



Candacia norvegica (Boeck), found in the cooler part of the Noj-th 

 Atlantic Ocean, appears to be limited to waters of lower temperature 

 than those surveyed by the Alaska and the Gill. In AVilson's Carnegie 

 and Albatross papers this species was reported to have been found in 

 the Sargasso and Caribbean regions and in many parts of the Pacific 

 Ocean. As in the case of C. armata, Wilson's determinations have 

 been found to be incorrect. C. norvegica was not present in any of 

 the Albatross or Carnegie material in the U. S. National Museum.

Localities and Material: Gulf of Mexico: Lat. 2o°35' N., long. 

 82°23' W. (USFWS Alaska cruise 4, station 29, Jan. 19, 1952, 1 meter 

 depth of tow, one female); lat. 23°31' N., long. 86°44' AV. {Alaska 

 cruise 4, station 36, Jan. 24, 1952, 1 meter depth of tow, one female). 



Gulf Stream: Off Florida coast, lat. 27°40' N., long. 79°41' W. 

 (USFWS Theodore N. Gill cruise 1, station G, Feb. 17, 1953, 60 meters 

 depth of tow, one female); oft' South Carolina coast, lat. 32°41' N., 

 long. 77°03' W. (Gill cruise 1, station 62, Mar. 3, 1953, 75 meters 

 depth of tow, one female, one male). 



Measurements: Ail measurements made from dorsal view along 

 midsagittal plane; cephalothorax measured from anteriormost margin 

 of forehead to posterior margin of intersegmental fold between thoracic 

 fusion segment IV-V and genital segment; length of abdomen from 

 anterior margin of genital segment to articulation between fifth 

 innermost seta and right f ureal ramus. Measurements made at lOOX 

 magnification with aid of ocular micrometer, specimens immersed in 

 solution of 50 i)ercont glycerine, 50 percent water. Slender glass rods 

 used to support cephalothorax and abdomen in horizontal position 

 during measurements of each. 



The total length and cephalothorax-abdomen ratio, i)resented in 

 that order, for individuals collected at diflen^it localities are as 

 follows: Adult females: holotA'pe, 2.92 mm., 4.1 : 1; paratj^pes, 2.54
