of this species, but Sauvage kept it distinct, and gave some 

 admirable figures of it. These certainly show that it differs from 

 S. dichotoma, but seem to me to bring it within the range of 

 S. dichotomoides. It has the bulging pyriform zocecia, and slightly 

 raised peristomes, irregular transverse ridges of that species. 



Vine has referred a series of specimens from Thrapston to four 

 different species, two of which were new. His collection is 

 now in the British Museum, but his types cannot be recognized. 

 The whole series, however, seems to me to belong to S. dichoto- 

 moides. The figure on PL XII. Fig. 5 is referred in the text to 

 S. waltoni, and in the description of the plate to S. dichotoma; 

 but it is equally unlike both, having the pyriform zocecia of 

 S. dickotomoides.
