South American Rotifera. By J. Murray. 23T 



P. triangularis Murray (^4)- 



Discovered in Peru in 1911, the species is widely distributed 

 from the Tropics to the Straits of Magellan, but it is not yet 

 known in any other continent. It occurs in Punta Arenas, Chile ; 

 Buenos Ayres, Argentina ; and Eio de Janeiro, Brazil. 



Gallidina formosa Murray. 



Bolivia and Brazil ; characteristic of warm countries, tropical 

 and subtropical — India, Africa, Australia — at altitude of 11,000 

 feet near Pelechuco, Bolivia. 



C. punctata Murray. 



Like the last, this species is only known in warm regions — 

 Africa, Australia, Pacific Islands. In South America it only 

 occurred once, at Santa Cruz in the Tuichi valley, Bolivia. 



C. speciosa Murray. 



There are only three records of this species : — British Guiana ; 

 Pelechuco (altitude 11,000 feet), Bolivia ; British Columbia. They 

 are all mountainous regions. 



C. vesicularis Murray (16). 



Tigre, near Buenos Ayres, Argentina. Previously known only 

 from three specimens collected by Mr. Bryce in Norfolk. Three 

 blunt toes were seen, making certain of the genus. The flame - 

 cells, though broad, were not inflated as in the original specimens. 

 Probably those were in pathological condition. 



C. pacifica Murray (.^^). Plate IX, fig. 3. 



Previously known only from a single specimen obtained in the 

 Fiji Islands, it turned up again abundantly on the top of Corcovada 

 mountain, Kio de Janeiro. I was able to make a study of the 

 animal in the crawling attitude. 



C. multispinosa Thomp. (29). 



A great many varieties, or races, of this species were observed, 

 of which I figure four of the most distinct. 



Some varieties approach the type, others belong to the short- 

 spined group ; several resemble varieties which I have figured in 

 various papers, but always with some differences. It is impossible 

 to figure all of these, but I hope to mak^a special study of them 

 elsewhere.
