Chylus cells (p1. xvii, fig. 2) .—These cells, wliich occur in three somites posterior to clitellum, are long and narrow. The inner duct is digitate at the base. The chylus cells broad and shallow epithelial cells. Spermatheca with a sac- like apical pouch, without di- verticles; connects with the in- testine, the stem of the sperma- theca much twisted. Penial bulb small, with cells opening both into the sperm-duct and at the base of the papilla. Lymphocytes round, disc-like. Nephridia with a long and nar- row anteseptal. Color yellow- ish-white. Locality.—Santa Cruz Mountains near Boulder Creek, on ranch of Mr. Koester, Prof. Charles Fuchs. Characteristics.—Exteriorly the species is readily distin- guished. The anterior four to while all those posterior are jDer-.
