bad a length of 4"™, the radula-sheath projected behind at the lower side. The brownish 

 mandible plates had a height (length) of 1°™, by a breadth of up to 0'28 mm ; their elements 

 (fig. 12) which were a little bent, were angularly cylindric. of a height of up to - 020 mm , 

 closely set. The palatal hooks Ifig. 13) of the upper wall of the buccal cavity were of the 

 common form, of a length of up to O'C^o™ 11 . yellowish. A countless number of glands 

 were found everywhere on the walls of the buccal cavity. The powerful tongue had a 

 glittering, brown radula; when spread out this latter had. together with the radula-sheath, 

 a length of 3™™. In the radula which was anteriorly highly tapering, 32 series of tooth 

 plates were found, in the sheath 12 developed series and 4 undeveloped ones; thus the 

 total number of series was 48. In the hindmost series of the tongue about 68 lateral 

 plates were found on either side of the median ones. The plates were yellow, only the 

 outermost ones were colourless. The breadth of the median plates was O - ^ 1 ™ 1 ; the height 

 of the hook of the three outermost lateral ones was 0"05— 0'055 — O-OB™ 111 , and the height 

 rose by and by to O'OS™ 11 . The median plates Ifig. 14i were of the common form, with 

 highly spread legs ; on either side of the point one somewhat stronger denticle and two 

 smaller ones were found. The inner lateral plates were also of the common form (fig. 14) 

 with two truncate hooks: on the outer edge of the first still two small denticles were 

 found, on the following (5 — 6) ones only one denticle, which then disappeared, while the 

 cleft between the hooks deepened, and these latter became longer ifig. 15); on the outer- 

 most plates only a trace of the cleft was found ifig. 16). 



The salivary glands were 6 1 ™ 1 long, whitish, somewhat thicker posteriorly, at- 

 tached to the fore half part of the masticatory stomach. 



The oesophagus was posteriorly developed into a proventricle showing strong 

 folds with soft tufts. The masticatory stomach was short-pyriform, of a diameter of 

 3mm ; ver y muscular and somewhat tendinous glittering; it contained the common, here 

 slightly yellowish, pyramidal masticatory plates, arranged in the usual way, to a number 

 of 12, of which 9 were large, of a height of up to l 1 ™ 1 . In the cardial part of the 

 posterior stomach some series of hooks were found ifig. 17); they were high, little stiff, 

 almost colourless, very finely streaked longitudinally, straight or somewhat bent, truncate 

 or pointed, and had a height of at least up to Odo™ 11 , by a diameter at the base of up 

 to O- 12°™. 



The dirtily brown liver had a length of 12 mm . by a diameter of 4°™; it was 

 conical. 



The penis had a length of 4 - 5 imn , by a diameter at the somewhat thicker upper 

 end of O'S" 1111 ; it was grayish: the praeputium was provided with fine longitudinal folds, 

 and a stronger furrow; the glans was almost l™ 11 long, conical; at its base, as also at 

 the top of the praeputium some few. not hard cones (fig. 18) of a height of up to 0"12 nan .
