190 BULLETIN OF THE BUREAU OF FISHERIES. 



is very long, perhaps longer than the longest cirri, and ii is apparently nol annulated. Then- is a tuft 

 of hairs at the end and Borne sparse, short hairs along its length. 



Type, no. 32-107 (hard part) and no. 32408 (soft pari i U. S. National Museum, from Albatross station 

 3998, vicinity of Kauai Island, in 228 to 235 fathoms, on bottom of coarse, broken coral, sand, shells, and 

 nick; with Poscilasma helium, Alepas percarinata. and a few small odd valves of Verruca halotheca. 



Fragments of two or three individuals were taken, the largest and must perfect being drawn in 

 plate v, figures 1 and 2. in which the following plates are preserved in place: Carina (ci, carino-lateral 

 I CI.), terga(T), scuta (S); and in another individual the rostrum (R). rostro-lateral (Rl), and four plates 

 of the third whorl. Figures 3 (top view of carina) and 5 (anterior view of rostrum) represent detached 

 valves of another individual or individuals. 



BALANIDjE. 



Balanus amphitrite Darwin. 

 Balanus amphitrite Darwin, Monograph on the Balanitis, p. 240. 



Some small specimens taken from the bottom of a tug at Honolulu are similar externally to figure 2e 

 of plate v of Darwin's Monograph, except that the compartments diverge less above, the aperture being 

 somewhat smaller and hardly dentate. The basal length of the largest specimen is 15 mm. The terga 

 resemble figure 2k of the same plate. 



It is difficult to pronounce upon the subspecies or variety of B. amphitrite to which these specimens 

 are referable. They are probably not full grown, and a much larger gathering would be essential for 

 a satisfactory study of the Hawaiian race. 



Balanus sp. 



The tangles brought up numerous Cidaris-like spines encrusted witli small barnacles 2 to :', mm. in 

 diameter, at station 4062, northeast coast of Hawaii, 83 to 113 fathoms. They are too young to be identi- 

 fied with certainty.
