Notes on Victorian Rotifers. 7^ 



Family PterodinadtE. 



(1) Pferodina intermedia. Brighton. Of this species 

 only one specimen was seen, but the " semi-circular pio- 

 jection " at the anterior was distinctly visible. It is 

 interestino- to find here this species, which was first noted 

 l^y my colleague as occurring among Indian rotifei's {Jour. 

 Asiatic Soc", Bengal, Vol. LVII, Part II, No. 4, 1889). 

 —J. S.] 



(li) Fterodina trilohata (n. sp.) Sandringham. This 

 specimen differs from any described species in the form of 

 the dorsal plate of the lorica, it having the semicircular 

 projection in front, with two broad bulgings on either side, 

 giving it a tri-lobed appearance. The lorica is stippled, and 

 so far as observed, inflexible. The coronal discs are widely 

 separate, and there is a notch at the base of each disc, giving 

 the median portion the form of a short broad lip. The 

 gastric glands, so conspicuous in the genus, escaped observa- 

 tion, probably owing to the stippling of the lorica. Length 

 of lorica -4^th in., extended xioth in., breadth ^^oth in. —
