Show 902 MR. F. E. BEDDARD ON THE [Dec 4, no terminal sac to their duct. Spermathecae 8 to 10 pairs in vi. and vii. Hab. Malay Peninsula. It is clear that this species comes nearest to A. stelleri, from which, however, it can readily be differentiated by the nature and position of the genital papillae. (10) Amyntas kelantanensis, sp. n. (Fig. 4, p. 903.) I have examined some thirty individuals of this new species, which cannot be confused with any of its allies. It is a long and slender species, measuring up to 105 m m . in length by about 3 m m . in breadth. The number of segments in the longest individual is 100. The setce on the anterior segments are fewer and larger than those upon tbe following segments. The clitellum occupies fully its usual segments and is entirely without setae. Genital papillce are rarely to be seen. W h e n present (fig. 4, p. 903) they consist of three pairs of whitish round patches, one pair on each of segments vi.-viii., lying in front of the line of division between each segment and that which follows. They are related to stalked glands, which will be described when the internal viscera are treated of. The male pores are conspicuous and widely separated. There are about a dozen setae between them. The gizzard-septa appear to be absent. The last heart is in the xiiith segment. The large intestine begins in segment xv., and has the usual pair of cceca, which are of fair length. The sperm-sacs are racemose in form and lie in segments xi. and xii. The spermiducal glands extend from segment xvii. to xxi. They are much broken up into lobules ; that part of the gland which lies behind the male pores is wider from side to side than the part lying anterior to them. The duct is not particularly long and is coiled into a circle. There is no terminal sac The spermathecce are present to the number of three pairs and are situated in segments vii., viii., ix. The pouch has a round or oval contour and communicates with the exterior by a duct which is almost as long as the pouch. Tbe diverticulum has a characteristic form ; it is very long and if unwrapped would be considerably longer than the spermathecae. The greater part of the diverticulum is much coiled, and it is dilated at its extremity into an oval chamber; the muscular duct is comparatively short. A n oval gland, whiter in colour than the diverticulum and with a long stalk, opens in common with the spermathecal duct. The arrangement,in fact,is very like that of Amyntas houlleti,with which species, however, there is no possibility of confusing the present. Hab. Aring, Kelantan.
