Remarkable Flagellate from Hind-gut of Termite. — D. Ward 

 Cutler {Quart. Journ. Micr. Sci., 1919, 63, 555-88, 9 pis., 3 figs.). 

 A description is given of Ditrichomonas (Trichomonas) termitis g. et. sp. n., 

 from the hind-gut of Archotermopsis ■wroughtoni, an Indian termite. At 

 the anterior end there are two free flagella springing from a blepharo- 

 plast, and a posteriorly-directed one forming the border of the un- 

 dulating membrane and arising from a special granule. There is a 

 cytostome. An axostyle runs through the whole length and emerges 

 at the posterior end. An elongate parabasal body with a central 

 thread springs from the blepharoplast. Multiplication by simple division 

 was observed. There is division of the blepharoplast, of the membrane- 

 granule, probably of the parabasal body, and probably of the axostyle.

Ciliata from Intestine of the Gondi. — Edouard Chatton and 

 Ch. Perard {Bull. Soc. Zool. France, 1919, 44, 10-17). In the 

 cgecum and colon of Ctenodactylus gundi, a rodent of the Sahara borders 

 and Southern Tunisia, the investigators found immense numbers of 

 two new Ciliata, Nicoldla ctenodactyli g. etsp. n., and Colinella gondii 

 g. et sp. n. The first form shows a very large contractile vacuole at 

 the posterior pole ; a sub-median mouth ; three zones in the ectoplasm ; 

 a vacuolated endoplasm ; a micronucleus more or less embedded in 

 the macronucleus. It multiplies by oblique sub-transverse division. 

 Conjugation was studied. In the second form the mouth is posterior, 

 and so is the contractile vacuole, otherwise there is close resemblance 

 between the two genera. They seem to require a new family,
