Bradyetes florenSf new species 



Figures 46-54 



Occurrence: Station 338 NV, 2000 to 1000 m, 1 9. 



Diagnosis (female) : Head and first thoracic segment incompletely 

 separate, fom'tli and fifth thoracic segments separate. Fifth tho- 

 racic segment rounded. Rostrum absent. First antenna reaches to end 

 of furca. Terminal five segments of maxilliped equal in length to 

 second basal segment. First and second exopodal segments of 

 first foot without external spines. Total length 1.10 mm. Holotype 

 USNM 113516. 



Remarks: This species differs from B. inermis FaiTan and B. 

 hrevis Farran, the only described species in this genus, by the rel- 

 atively short first and second basal segments of the maxilliped, 

 by the absence of a spine on the fu"st exopodal segment of the fu'st 

 foot, and by its small size. 



Chirundinella cara Tanaka, 1957 



Figure 55 



Remarks: The only difference between this specimen and the 

 description given by Tanaka (1957) are 11 rather than 10 setae on the 

 endopod of the first maxilla and 3 rather than 4 setae on the fifth lobe 

 of the second maxilla. Our specimen measured 7.80 mm, Tanaka's 

 measured 7.44 mm. This species has not heretofore been found in 

 the Indian Ocean. 



Gaetanus brachyurus Sars, 1907 



Remarks: The female specimen from station 131 differs from the 

 others and from the description of this species in having the exopod of 

 the first foot consisting of two segments. Each segment has one 

 external spine. The animal is also smaller (5.00 mm). The other two 

 females found measured 6.17 and 6.42 mm. Gaetanus hrachyurus has 

 not previously been found in the Indian Ocean. 



Gaetanus /erox With, 1913 



Figures 56-59 



Remarks: Although the right exopod of the fifth foot of the male 

 is 3-segmented in our specimen (With, 1915, shows two segments), 

 the terminal portion of the exopod is similar to With's figure. Pos- 

 sibly the suture separating the two terminal segments was not ob- 

 served by him. Our specimen measured 3.55 mm; With's measured 

 3.4 mm. This species has not previously been reported from the 

 Indian Ocean.
