That Ehrenberg's Notommata forficata (forcipata in his "Infusions- 

 thierchen" is an inadmissible correction) is the same as Gosse's 

 Diaschiza pseta seems beyond question; the long, slender toes, wide 

 apart at the base, often crossed, size 0.15 mm., and the very large 

 "eye," that is, gastric glands, all agree very closely with Gosse's 

 description.
