one would imagine to be of more use to an eartliworm than an 

 organ of taste. 



The pharynx begins in Segment 4. Septal glands are well 

 developed. In Segments 6 and 7 are gizzards — one to each 

 segment, with tolerably thick muscular walls. The oesophagus 

 extends as far back as the end of the 11th segment; in the 

 next segment the intestine commences. The calibre of the 

 oesophagus is less than half that of the intestine ; it is fur- 

 nished in Segment 9 with a pair of diverticula which appear 

 to be very like those of Pygmseodrilus quilimanensis: 

 the basal part where they arise from the oesophagus is wide, 

 but the pouches narrow towards the free extremity, which is 

 obtusely pointed. The structure is that of the calciferous 

 glands of other earthworms. 



Generative Organs. — These are somewhat intermediate 

 between those of a new genus, Gordiodrilus, recently de- 

 scribed by myself, and other Cryptodrilida;. There are only a 

 single pair of testes, which are, as is the case generally among 

 earthworms when there is only a single pair, in Segment 11 ; 

 the sperm-sacs are in Segment 12, and are of a racemose 

 form ; in Segment 11 also there was a mass of developing 

 sperm. The ovaries are in the 13th segment ; the oviducts 

 are perfectly normal, and there are no egg- sacs. The sperm - 

 ducts in correspondence with the testes are a single pair, the 

 funnels lying of course in Segment 11. The sperm-duct of 

 each side passes back close to the peritoneum of the ventral 

 body-wall; arrived at the 17th segment the sperm-duct perfo- 

 rates the body-wall ; just before entering the body-wall it 

 becomes slightly wider, and is invested by a moderately thick 

 muscular tunic ; but the lining epithelium is still ciliated. 

 The sperm-duct at this part of its course lies behind the 

 atrium ; when it enters the body-wall it passes obliquely in a 

 slightly forward direction, and opens into the duct of the 

 atrium just before the external orifice of the latter, and on to 

 its posterior side. The atria are a single pair of tubular 

 bodies, which consist, as in most earthworms, of a distal mus- 

 cular portion and of a proximal glandular portion. The
