Show 904 MR. F. B. BEDDARD ON THE [DeC. 4, (11) Amyntas pulauensis, n. sp. (Fig. 5, p. 905.) The present species is represented by a number of specimens, all of which do not show7 the principal diagnostic character of the species, and led m e to confuse it with Dr. Horst's Amyntas bosschee, from which it appears to be perfectly distinct, provided that there are no lacuna) in the descriptions given by Horst1 and Michaelsen2. The length of the largest individual is 165 mm.; the number of segments I am unable to state with accuracy. The clitellum occupies the whole of segments xiv.-xvi. and appears to have no setae upon it. The genital papillce are the distinguishing feature of the species so far as concerns external characters. On segments xvii. and xviii. in front of the line of setae is an area which presents the appearance of a sieve owing to the presence of 40-50 pore-like depressions, which are the external expression of numerous white glands which are visible on dissection. These groups of papillae are median and unpaired. There appears to be a similar area upon the viith, viiith, and ixth segments, which is very like that of A. hilgendorffi as figured by myself 3. The male pores are very conspicuous and widely separated; 13 setae lie between them. The gizzard-septa are absent. The intestine begins in the xvith segment, and is furnished with a pair of cceca, which are rather short, barely reaching to the level of the xxvth segment. The last pair of hearts are in segment xiii. The sperm-sacs are large, solid, and compact. They lie in segments xi. and xii. The spermiducal glands are not of a compact structure ; they are much lobulated and occupy segments xvii.-xix. Their duct is short and thick and opens into a rounded, rather flattened terminal sac The spermathecie are four pairs and lie in segments vi.-ix. Each sac is oval or more or less pear-shaped iu outline; its duct is sharply marked off and about j tbe length of the sac. The diverticulum is not large and not a great deal longer than the duct of the spermatheca. It is divisible into an oval sperm-holding receptacle and a narrower folded duct. Hab. Pulau, Bidang, Kelah, and Aring. The following is a brief definition of Amgntas pulauensis, n. sp. Length 165 mm. Clitellum xiv.-xvi, without sets. Genital papillae median unpaired group of pores upon viii., ix., xvii., xviii., in front of setae. Male pores large and far apart. Septum viii./ix. absent. Last heart in xiii. Caeca present. Sperm-sacs xi., xii. 1 Notes Leyden Mus. xv. p. 324. 2 Abh. Senck. nat. Gres. xxiii. p. 238. 8 Zool. Jahrb., Abth. f. Syst. vi. pi. fig. 1. |
