are comparatively slender and composed of two unequal joints, 

 the first being only about half the length of the second. The 

 first joint of the fifth pair is short, the second large and 

 foliaceous, thickly covered with cilia, and furnished with four 

 subterminal setae. The abdomen and stylets together are 

 only about one third the length of the cephalothorax. Caudal 

 stylets nearly equal to the combined length of the last two 

 abdominal segments. The base of the principal seta of each 

 stylet is considerably enlarged and is articulated to the elon- 

 gate slender distal portion.

Bemarks. This curious species resembles some of the 

 Lichomolgidee in general appearance, but it differs from any- 

 thing known to us in the rudimentary structure of the mouth- 

 appendages and in having the inner branches of all the first 

 four thoracic feet two-jointed. Though obtained among 

 dredged material, its structure clearly indicates semiparasitic 

 habits similar to the Lichomolgidge and other closely allied 

 forms ; but its host is at present unknown to us.

One specimen of this curious species has recently been 

 obtained among dredged material from the Moray Firth, 

 depth 130 fath. 



The structure of the anterior antennse, with their extremely 

 long filamentous hairs^ and the structure of the posterior foot- 

 jaws and first thoracic feet enable the species to be readily 

 distinguished. The species was described by Dr. Glaus from 

 a single specimen in 1889 (see op. cit.), and, so far as we 

 know, this is the only other record of its occurrence. Dr.
