Concerning the internal anatomy can be stated, that the 

 first septum is situated between segment V and VI; this and the two 

 succeeding dissepiments are specially thickened and connected with 

 each other by numerous muscle-fascicles. The 8th and 9th septum 

 are absent; the 10th, 11th, 12th and 13th are however rather 

 thick. 



The pharynx reaches till segment IV; it is entirely covered with 

 glands and muscular fibres, radiating in all directions to the body- 

 wall. Next to it follows the oesophagus, which extends as far as the 

 posterior septum of segment VII. In segment V and VI there occur 

 on each side of the oesophagus large groups of spirally coiled glan- 

 dular tubes (Perrier mentions them also of segment VII); in both 

 segments I found also on each side of the dorsal vessel, situated 

 around a muscular band, connecting the anterior and the posterior 

 septum of the relative segments, a conical glandular body, the so- 

 called „blood-gland" of Beddard. 



The segments VIII— X are occupied by the gizzard, which is some- 

 what barrel-shaped ; on its dorsal side , nearly at two thirds of its 

 length a row of longitudinal muscles are inserted, which pass back- 

 wards to the next septum and undoubtedly act as retractors of the 

 intestinal canal. The tubular intestine has its wall glandularly thickened 

 in segments XI — XIV; the sacculated intestine commences in segment 

 XV, and is in segment XXVI provided with a pair of long coeca, 

 extending forwards till the prostate. 



The shape of the spermathecae, situated in segment VII , VIII and 

 IX, very well agrees with the drawing ') published by Perrier ; afterwards 

 they have been figured also by Bourne 2 ) and Beddard 3 ). Each spermatheca 

 consists of (1) a long , tongue-shaped pouch , with short duct , (2) a tubular 

 diverticulum coiled in a zigzag line, nearly half as long as the pouch, 

 and (3) a small long-stalked globular body. In the present examples I 

 found that the first pair of spermathecae possesses only one globular 

 body, but the two other pairs have a greater number of them, viz. 3, 

 4 or 5. Perrier only mentions a single „poche glandulaire bilobée," 

 as also figured by Bourne; Beddard however sometimes found a pair
