Spec. Char. — Body long, more or less cylindrical, laterally com- 

 pressed ; head sub-conical ; neck well marked ; face sub-prone ; 

 corona extending right down to neck ; lorica flexible ; dorsal cleft 

 well marked, deep ; lateral cleft well marked, wide ; eye wanting ; 

 foot short, thick ; toes about § rest of body, furcate, style-shaped, 

 acute, re-curved, wide apart at base ; gastric glands in adult 

 tinted red. 



This Diaschiza is the first of the group which possesses no red 

 eye, and is of the long, laterally compressed type. The lorica is 

 very flexible, especially on the ventral surface, which is conse- 

 quently sometimes fiat, sometimes slightly concave. 



The dorsal and lateral clefts are, in spite of this flexibility of 

 the lorica, deep and well marked. 



The foot projects considerably from under the lorica, and carries 

 two toes wide apart at their base when viewed dorsally. 



These toes are long, blade-shaped rods, with a fairly bold curve 

 upward and outward. 



The setae on the foot, usually four, are very long in this species, 

 often half as long as the toes. 



The jaws have the incus long, the fulcrum large, and the 

 manubria ending in a somewhat crutch-shaped club. 



The adults have the gastric glands filled with red pigmented 

 granules, which were mistaken by Gosse for a very large globose 

 eye, hence he re-described this species as D. pceta. 



They lie one on each side of an untinted, long brain-sac, which 

 shows distinct cellular construction, but no vestige of an eye- 

 spot. 



In many young examples, which vary tremendously in size, all 

 trace of the tint in the gastric glands is absent, and, in our opinion, 

 it was from one of these immature examples that Gosse first de- 

 scribed this species. 



His description of F. cozca is correct as far as it goes.
