the terga in shape, but only three-fourths as long; their tips 

 turned outwards and projecting laterally, their inner margin 

 overlapping the occludent margin of the terga for a consider- 

 able distance. Rostrum prominent, triangular, recurved. 

 The two subrostals similar in shape, but smaller and much 

 less prominent ; the lower valve larger and more prominent 

 than the upper. Latera transverse, triangular, of no great 

 size, prominent at the tips. Subcarina resembling the 

 rostrum, but less than half as long. 



Peduncle much shorter than the capitulum, compressed, 

 almost triangular in lateral view, covered with almost nodular 

 subimbricate plates arranged somewhat irregularly. 



Ciri-i very long and slender, feebly curved, colourless.

The external characters of this barnacle are so peculiar 

 that I have ventured to describe it without dissecting the 

 unique specimen, on which I have not succeeded in finding 

 any degenerate males. I understand that this specimen will 

 be deposited in the British Museum.

 Belly greyish, the bases of the hairs slaty, their tips greyish 

 white. Hands and feet dull whitish. Tail long, very finely 

 haired, so as to appear naked. Mammae 2 — 2 = 8.
