Show 646 MR. F. E. BEDDARD ON THE [May 22, latter, however, may have setae (in addition to those upon xiv.) on xv. The papillae may be anterior as well as posterior as in hawayanus; 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 spermathecae are in vi., vii., or in vii., viii. There are anterior and posterior papillae. In P. mauritiana there are three pairs of spermatheca? in vi.-viii.; in one individual I found a fourth pouch on one side of the body in ix. The seta? 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 Michaelsen 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 with hawayanus. As to the former matter, it would be necessary for m e to separate one of the individuals wiiich 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 '4 ziemlich weit von einander." I think that there is every reason to accept Michaelsen's identification 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 seta? 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. D. Spermathecae 3 pairs in segments vii.-ix. 93. Amyntas hupeiensis Mich. Perichceta huqyeiensis,Michaelsen, Abh.Ver. Hamb. xiii. No. 2, p. 35. Amyntas hupeiensis, id. Jahrb. Hamb. wiss. Anst. xvi. p. 6. 55 mm., 132 segments. Seta? closer ventrally, and larger ventrally on anterior segment, 95 on x., 72 on xxvi. Setaa 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.
