latter, however, may have setae (in addition to those upon xi v.) on xvi. & 

 xv. The papillae may be anterior as well as posterior as inhawayanus; 

 the setae of some of the anterior segments are enlarged as in 

 that form. The spermathecae are occasionally reduced to two pairs, 

 in vi., vii. ; but as the usual three are to be found, no specific 

 difference can be made upon this point. P. morrisi differs only in 

 the fact that the sperrnathecae are in vi., vii., or in vii., viii. There 

 are anterior and posterior papillae. In P. mauritiana there are 

 three pairs of spermathecae in vi.— viii. ; in one individual I found 

 a fourth pouch on one side of the body in ix. The setae on 

 segments iii.-vii. are larger than those on other segments. Thus 

 there are clearly no marked differences to say the least from the 

 other forms which I here unite into a single species. P. pallida 

 of Michael sen cannot be plainly distinguished from the present 

 series. Michaelsen mentions the absence of the larger setae upon 

 the anterior segments, and the closer approximation of the male 

 pores as reasons for not confusing it witli liawayanus. As to the 

 former matter, it would be necessary for me to separate one of the 

 individuals which I have referred to barbadensis, if this were to be 

 considered a sufficient reason. As to the latter point, I do not 

 understand from Michaelsen's description that the male pores are 

 really close ; he speaks of them as " ziemlich weit von einander." 

 I think that there is every reason to accept Michaelsen's identifi- 

 cation of amazonica with his pallida. And my own form sancti 

 jacobi can hardly be separated. Of both of these latter only a 

 single example has been examined. Of mandhorensis again only a 

 single example is known. But Dr. Michaelsen's description of 

 this specimen leaves no great doubt of its likeness to the worms of 

 the present series. It has larger setae on segments ii.-ix., as in 

 hawayanus ; the caeca have the crenated appearance of those of 

 the latter form ; the spermathecae occupy the same segments and 

 are of similar form. No anterior papillae appear to exist ; but as 

 only a single example was described, this cannot be considered a 

 reason for specific separation.

55 mm., 132 segments. Setae closer ventrally, and larger 

 ventrally on anterior segment, 95 on x., 72 on xxvi. SetaB 

 ventrally on all segments of clitellum. Male pores rather close 

 together. Papillae before and behind each male pore and two 

 pairs on xvii./xviii., xviii./xix. Septa viii./ix., ix./x., very thick. 

 Spermiducal glands in xvii.- xx., with thin winding duct. Sperma-
