and less obliquel) wedge >hap< I distally, and finally oblong and elongate. All the brachials 

 are perfectly smooth, with no ornamentation of any kind. 



Syzygies occur between the third and fourth, ninth and tenth and fourteenth and fifteenth 

 hials, and distally at intervals of two oblique muscular articulations. 



1', is u tnm. long, very flexible and slender, composed of 35 40 short segments most 

 of which are about as 1 broad with all the angles cut away and hence appearing 



rounded, those in the terminal third becoming slightly elongated; the articulations are enlai 

 and the whole pinnule suggests a string of small beads. 1' is 5 mm. long with 12- 15 segments 

 of which the first two are about as long as broad, and the fourth and following rapidl) become 

 elongated, and very slender distall)-: the fifth, sixth and seventh segments ln-ar a large rounded 

 genital gland; the following pinnules to P 8 are similar, but the genital gland gradually moves 

 nearer the base of the pinnule. on 1', extending from the third to the sixth segment. The 

 distal pinnules are 12 mm. long with 20 segments of which the first is very short, almost 

 band-like, the second is almost triangular, the third is about half again as long as broad, the 

 fourth is about twice as long as broad, and the remainder become progressively elongated. 



Thi ir in spirits is yellowish white, with a large black spot on each side of each 



ygial pair; the inner half of the articular faces of the syzygies is also black. 



The specimen described is Cat. N° 22675 U. S. National Museum.
