Another New Branchiate Oligochæte


ABOUT two years since I described in the columns of this journal (vol. xiv. p. 109) an Annelid belonging to the family Tubificidæ, which was unique in that family in the possession of a series of branchial processes upon the posterior segments of the body. This worm, as I reminded the readers of NATURE on Jan. 11 (vol. xlix. p. 247) was found in the “Victoria Regia tank” at the Botanical Society's Gardens—a locality which has produced many interesting invertebrate animals. I have now to record the existence of another Oligochætous Annelid in which branchial processes of a very similar nature to those of Branchiura Sowerbii are found. This worm was sent to me by Dr. Michaelsen, of Hamburg, a well-known authority upon this group of animals; it had been collected by him in South America during a recent expedition for collecting purposes to that country. With great generosity he has handed over to me for study the bulk of the Oligochæta which were brought home by him from Patagonia, the Argentine, and Chili; and the species upon which I desire to say a few words here was among those worms. It was discovered in the river at Valdivia, in Chili.
