SOME ROTIFERA OF THE FORTH AREA 89 



Most of the others are common and widely distributed 

 species, which call for no remark. 



Like the previous list of Bdelloida (6) this list of non- 

 bdelloid Rotifera is entirely founded on Mr. Evans's collections. 



References to the short list of works cited at the end of this 

 paper are made in the text by figures in thick type enclosed 

 in parentheses. 



LIST OF SPECIES. 



RHIZOTA. 

 Family FLOSCULARIAD^E. 



Floscidaria ambigua, Huds. Upper Elf Loch, Braid Hills, November 

 ^OS- 

 Family MELICERTADjE. 



CEcistes crystallinus, Ehr. Bavelaw Moss, February 1905. 



PLOIMA. 



Family HYDATINAD^E. 

 Notops hyptopus, Ehr. Hopetoun Woods, December, 1905. 



Family NOTOMMATAD^E. 



Notommata aurita, Ehr. Near Doune, Upper Elf Loch, Winchburgh. 



Furailaria /ongisefa, Ehr. Bavelaw Moss. 



f. reinhardti, Ehr. Torduff and Nether Habbie's Howe (Pentland 

 Hills), Winchburgh. The species, or the closely related Notom- 

 mata theodora, Gosse, if the two are not identical, is frequent in 

 the open water of lochs. Except in the matter of size, which 

 is variable in the species, I can see no difference between the 

 lacustrine form and that which Mr. Evans got in moss from 

 the three localities mentioned above. 



F. forfiada, Ehr. (2). Near Doune, Upper Elf Loch. 



Diglena forcipata, Ehr. Upper Elf Loch ; Pond near Winchburgh, 

 December 1905 ; Marl-pit at Davidson's Mains, February 1906. 



D. dromius, Glascott. This very large member of the genus was 

 identified by Mr. Rousselet from a drawing sent to him. 

 Malleny Dam, near Balerno, February 1905. 



-D. rosa, Gosse (3) (? = Taphrocampa sai/tidersice, Gosse). An 

 anomalous animal, combining the characters of two sufficiently 

 remote genera. Marl-pit at Davidson's Mains, near Edinburgh, 

 February 1906. 



Proales wernecki, Ehr. Ditch near Bavelaw Castle, March 1906. 

 A remarkable parasite making galls on Vaucheria.
