It is rather curious that in an appendix to my account of the earthworms of the 

 Sandwich Islands 1 should have described from Barbados a species which I regarded 

 as new and described as Perichaeta trityphla. Curious since I have subsequently found 

 many specimens of this worm in gatherings from Honolulu at 2000 feet of altitude and 

 also in earth imported from Hong Kong. I think that Michaelsen' is probably right in 

 identifying my trityphla with the long known species schmardae. But at the same time 

 it must be borne in mind that the condition of the caeca, which I thought to be distinc- 

 tive of trityphla, has not been described in the original specimens of schmardae. 

 These caeca, I may say, vary in number from three to si.x on each side, and the two 

 sides are not always symmetrical in this respect. The occurrence of such caeca seems 

 to mark the species as a native of Japan — one of the most prominent characteristics of 

 the species of that island being the frequent complication of the caeca. I think that 

 there can be no doubt that Perichaeta vesiculata of Goto and Hatai is the same species. 

 There is positively no feature in their rather short description of the so-called vesiculata, 

 which does not fit in with the facts observed in the anatomy oi schmardae and ti-ityphla.
