74 W. MILNE ON THE 



The egg is a flat oval, with thirteen lateral prominences, or 

 rather gentle swellings, three at the end are larger than the others. 

 It is not unlike the egg of P. plena. 



The only species at all like this one is P. plena. They are both 

 tubby-looking animals when feeding, and have spurs and upper 

 lips somewhat similar ; but the peculiar shape of the foot and also 

 of the first two trunk segments, the proportions of the corona, 

 and the presence of the flanges, easily serve to distinguish P. 

 patula from P. plena. 



Habitat. — Ground moss, Grahamstown and Springfield Uiten- 

 hage district. Found abundantly, on one occasion only from 

 each place. 



Philodina rapida sp. nov. 

 PL 4, figs. S-Sa. 



Specific Characters. — Of fairly large size ; yellowish in colour. 

 Heavy neck and lumbar region, with short stout foot. Antenna 

 stout, and equal to one-half neck width. Teeth, three, medium 

 size. Intestine very large. Foot consists of three segments. 

 Spurs parallel and very short. Corona large with wide sulcus. 

 Upper lip trifid. Size, l/70th inch. 



This species in general appearance is not unlike a Macrotrachela. 

 Its heavy lumbar region and stout short foot chiefly contribute to 

 the resemblance. It also creeps fairly fast after the style of a 

 Macrotrachela. The rostrum is fairly stout and has several long 

 setae, a double but rather small lamella, and cilia which have a 

 habit of moving slowly when the animal is feeding. A thick 

 antenna bears short stubby setae. There are three medium- sized 

 teeth in the dental bulb, which is not very large. 



The trunk is plicate and strongly muscular. Large glands 

 extend through the foot and far up into the lumbar region. The 

 intestine is extremely large, and the contractile vesicle of medium 

 size, with a not very short period. The spurs are very short and 

 parallel, with a concave line joining their tips. They very much 

 resemble those of P. patula. The foot is very short, and of, 

 apparently, three segments, and the toes are also short. 



The corona is a handsome one, and large — about one-fourth 

 of the extreme length of the body — while the sulcus is rather 

 wider than the disc (7 : 6'5). Corona to collar is as 20 : 13.
