slender duct proceeding from its hinder end opens into tlie- 

 former by a minute papillary orifice. 



Intestines. — The total length of intestine intervening between 

 the pylorus and cloacal aperture is, when unravelled, 29 cm. 

 Arranged in a few simple coils, and of relatively large calibre 

 throughout, the anterior portion is of rather larger calibre than 

 that of the posterior, having on an average a diameter of 5 cm. 

 as against 3-5 cm. to which it diminishes at the point where it is 

 shown as divided in fig. 1, r. It is slightly sacculated throughout, 

 rather more so in the anterior than the posterior segment, but 

 there is no marked external indication of a division between 

 parts corresponding to large and small intestines ; though, in the 

 interior, an indistinctly marked valve-like projection, situated at 

 a point about 10 cm. from the cloacal oritice, may indicate a 

 delimitation ; and a sacculation immediately succeeding this, rather 

 more conspicuous than those elsewhere, may indicate a caecum, 

 but in both respects the observations are of very uncertain value. 

 The mucous membrane throughout its whole length is soft and 

 macerated, and is completely separated, forming an internal cast 

 of the tube, which makes it impossible to distinguish the micro- 

 scopical details. 



Food. — The recognisable debris of the food is confined to the 

 posterior portions of the intestine, the upper containing only 

 granular or soft flocculent and disintegrated material. On 

 examining the former they are found to consist of insect remains, 

 amongst which is a small black ant almost entire. Our Presi- 

 dent, the Rev. Thomas Blackburn, has been good enough to 

 examine the fragments submitted to him, and he informs me that 

 they are portions of an orthopterous insect, probably those of a 

 species of mole-cricket. 



Stomach (Fig. 4). — This organ, which is evidently considerably 

 compressed and contracted, measuring l'7o cm. in its greatest 

 length by 1-25 cm. in its widest part, is extremely simple in 

 shape, the short segment of oesophagus which intervenes between 

 it and the diaphragm springing from nearly the middle of the 

 lesser curvature, so that about an equal length of the viscus lies 

 on each side of it. It is empty, and the parietes are thick and 

 muscular ; the mucous membrane, less decomposed than in the 

 intestines, being thrown into a few large longitudinal rugfe, which 

 end at the pylorus. Externally the position of the pylorus is 

 indicated by a circular constriction, to the intestinal side of 

 which an outlying strip of the pancreas is closely adherent. 



Pancreas. — The main mass of this organ lies in the usual 

 situation, but it is too decomposed for accurate description or for 

 determining the disposition of its duct.
