have described. Possibly the definition of the genus might be 

 stretched to admit these new species ; but on the other hand, the 

 second, which I have named Notopygos parvus, may not impro- 

 bably turn out to be the type of a new genus.

6. — Chloeia Macleati, sp. nov. 



The length, of this form is two and-a-half inches, and its 

 breadth three-quarters of an inch, including the setae of the feet. 

 It is of oval depressed form, pointed at both ends, but more 

 acute posteriorly. The caruncle is attached below to the first 

 two setiferous segments ; but its posterior free extremity pro- 

 jects as far back as the hinder border of the third segment. It 

 consists of a larger central and two smaller lateral longitudinal 

 folds, each covered with transverse corrugations. Along the 

 summit of the central fold runs an irregular dark line, continued 

 forwards to the central antenna. The central antenna or tentacle, 

 which arises from the anterior end of the caruncle, is much 

 larger than the antennas proper and palpi ; the antennae are 

 marked with an irregular longitudinal black stripe ; the palpi 

 are shorter and stouter, and pale in colour. The cephalic 

 segment is large and strongly bilobed inferiorly. On the ventral 

 surface of the second setiferous segment, just in front of each 

 angle of the mouth, is a large black spot on each side, and one 

 or two smaller ones. The first two pairs of feet have each a 

 black spot on their anterior surface ; in the third pair, this 

 becomes a black line crossing the foot from without inwards; im- 

 mediately behind which, in the fourth and succeeding segments, 

 appears a second and shorter line crossing the ventral tubercle in 

 the same direction. The branchiae, which begin on the fourtji 

 somatic segment, arise from the dorsal surface of the segments, 

 internal to the dorsal bundle of setae ; they are very large and 

 finely pinnatifid ; the stout main stem being black, and the 

 branches pale. 



There is no such marked pattern on the dorsal surface of the 

 body as in Ghlocia pulchella and G. flava ; there is, however, one 

 indistinct, broad, oblique, dark band internal to the branchiae ;
