(fig. 7). Dorsal vessel arising very definitely in 15/lG. Salivary 



glands (fig. 8) very characteristic, wide at the base, with two short 



branches and a long one extending to 



^jQ. Ccclom so full of large pellucid 



coipuscles, with dark granuhitions, that 



the uephridia were entirely masked. 



Very large ampulla to spermathecre, 



about half as long as the duct. Ses.silo 



glands or diverticula between ampulla 



and duct, but no glands at exterior 



opening as in F. emarginata.

British Bccord. — Cauldwell, Derbyshire, July 9, 1911 ; appears 

 to be closely related to /*'. callosa, but the salivary glands are re- 

 markable.

Yellowish green to the naked eye. Length, 12-15 mm., 60-65 

 segments ; set», 2 in front, bent internally, 1-2 behind. Head 

 rounded, not glandular ; segments striate, very transparent in 

 normal condition alive. Though adult, the girdle boundaries not 

 clearly defined, but extending through two-thirds of segment xiii. 

 Long salivary glands extending to septum 7/8 unbranched (fig. 9). 

 A large pear-sliaped ampulla to spermathecte, without diverticula 

 or glands, but with long ducts, and joining the intestine in a 

 very unusual position in segment 6/7 (fig. 10). Chloragogen 

 cells large, brown, not crowded, contrasting beautifully with the 

 light green coelomic corpuscles. These when crowded were a 

 decided green, and are a marked characteristic. Nephridia with 

 large duct, usually if not always springing from the middle of 

 the postseptal, which is about twice as long as the anteseptal, 

 the duct equalling both ante- and postseptal in length. Dorsal vessel 

 arising in 22/3 or 23/4 ; septa of segments vi-ix much thickened and 

 forced back. Ampulla of sperm- duct 2-3 times as long as broad ;
