626 ON SOME PAUEOPODA FROM N. S. WALES, 



ramus is narrower by the width of this process, and the upper 

 flagellum and globulus are borne apieally upon the flat top of this 

 narrower portion. The lower flagellum is about half the length 

 of the upper; and the latter is, in turn, about three-quarters of 

 the flagellum of the upper ramus. The upper ramus is thrice and 

 one-half as long as broad, and its breadth is about equal to that 

 of the distal portion of the lower. The two longer flagella have a 

 basal unringed portion at least as long as the rami to which they 

 are attached. The stalk of the globules, which is large, is about 

 once and one-half as long as its transverse diameter. 



I have found it extremely difficult to make satisfactory observa- 

 tions of the ventral surface, as I could not afford to injure my 

 specimens; but I have finally been able to compare this species 

 with Hansen's figures on all points except the anal plate, about the 

 distal portions of which I cannot be certain. The tergum of the 

 anal segment has the lateral hairs the same shape as, and longer 

 than, the submedian; otherwise, it agrees with Hansen's figure. 

 The sternum has a row of four hairs, the outer pair being stout, 

 and slightly plumose distally; the inner pair delicate, shorter, and 

 sharply ringed. The posterior ventral setae are more than twice 

 the length of the outer pair, and are only shortly plumose 

 distally. The anal plate is rounded basally, its sides narrowing 

 slightly backwards, and passing into two long processes, which 

 are separated from one another by a deeply incised cleft. A second 

 pair of wing-like processes seem to lie dorsal to the main body of 

 the plate. The distal ends of the main processes, I was unable to 

 observe satisfactorily. As far as I can judge, they end as in the 

 figure (Fig. 18), but it is quite possible that they may show some 

 such structure as that observed by Hansen. 



The legs are very short, and none of them have a metatarsus. 

 The hairs of coxa and trochanter are both like that of the tro- 

 chanter in Hansen's figure. The tarsus bears a single large claw, 

 with a very fine, hair-like, second claw anteriorly. The second tar- 

 sal hair mentioned by Hansen, is not present. 



The larger male measures 1-2 in length.
