"Entirely white. Body, antennae and legs finely granular. 

 Length, 2mm. Entirely of a uniform, opaque, alabaster white, 

 excepting the median part of the back, which is slightly tinted 

 with dark yellow and rather transparent. The bodv is clothed 

 with short hairs, more numerous on the antennse ; the whole sur- 

 face above and below, as well as the antennse and legs, covered 

 with a granulation, very fine and regular ; the granules in rounded 

 cones. The buccal cone is large, short, rounded at the tip, its 

 opening indicated by a very distinct little transverse slit; the 

 feet bear a single rather long claw : finally, the anal segment is 

 composed of three hemispherical tubercles (mamelons), a superior 

 and two inferior, at the center of which is the anus." I think 

 no one has mentioned the sense knobs on the antennal tips. 

 They are much as in Anurida tullbergi. The post-antennal or- 

 gans are situated rather high up on the head, instead of more lat- 

 erally as in the Aphoruras, and are rounded in outline, consist- 

 ing of 12 to 14 "tumores" of triangular shape, their longest points 

 extending inward toward the center of the ring. Nicolet remarks 

 a yellow tint down the middle of the back. Tullberg says most 

 of his specimens were entirely white, but a few found among 

 some rubbish thrown up by the sea were yellowish. The speci- 

 mens are so colorless that any yellow food matter in the intes- 

 tinal tract shows through very plainly, and may possibly have
