There are nine set® on the xvifcli segment of the body, 4 on one 

 side and 5 * on the other side ot' the median ventral line. On the 

 third, fourth, and fifth setigerous segments the setoe are very stout, 

 particularly on either side of the median ventral line. Those of the 

 first two segments are delicate, as are those which follow the fifth. 

 Fourteen setae lie between the male pores. 



The clitellum (xiv.-xvi.), as has beuu already remarked, has seta) 

 upon its last segment. 



The dorsal pores commence x./xi. 



The male pores lie in the line of setae ; close to each, but below 

 the line of setae, are two or three papillce in a straight line with 

 their fellows on each side of the body, but obliquely as regards its 

 transverse axis. 



The first seplum divides segments v. and vi. ; this and the next 

 two are thickened ; so are the first four following the gizzard, the 

 last of which divides segments xiii./xiv. 



The intestine begins in xv. ; the ca3ca, which lie in segment 

 xxvi., are short. 



The last heart is in segment xiii. 



The sperm-sacs lie in xi. and xii. ; in x. and xi. are the sperm- 

 reservoirs, containing funnels of spei'm-ducts. 



The spermiducal <jlund occupies segments xvii.-xxi. ; it is 

 flattened and lobulated ; the duct is long and curved, narrowing 

 towards the external orifice, which is not provided with a terminal 

 sac. 



The ovaries occupy the usual position. There are a pair of 

 elongated egg-sacs in both xiii. and xiv. 



The spermathecce are in vi., vii., viii. The oval pouch com- 

 municates with the exterior by a long duct longer than itself. 

 The diverticulum, ending in an oval dilatation, has a corkscrew-like 

 duct. This diverticulum, when straightened, is not far short of 

 the pouch in length. 



Ilab. Waimea, Molokai, and Mauna Loa, Hawaii. 



Remarks. — I have given a description of this species because tlie 

 individuals examined by myself depart slightly and in a few 

 particulars from the description given of Perichceta haivayana 

 by Dr. Eosa. The most noteworthy difference is apparently 

 the existence of seta? upon the last segment of the clitellum. 

 Dr. Eosa does not assert their absence, but would, I an) disposed to 

 think, have mentioned their presence were they existent. On the 

 other hand, his description of the intestinal ca;ca — " oine gefiederte, 

 durch zvvei Lappeiireihen vermittelte Gestalt erkennen lasseii " — 

 agrees entirely with my observations. Differences also in the 

 number of the setse iu certain segments, and in tiie number of the 

 thickened intersegmental septa, will appear on a comparison of 

 Dr. Eosa's account with mine. 



I have marked this species as one of those indigenous to Hawaii.
