Notaspis venustns (Berlese). (PI. VIII, fig. 33 a-b.) 



There is little doubt that a Notaspis found commonly on the sea-coast at 

 Mulranny is to be referred to this species, originally described from Norway 

 by Dr. Berlese under the name of Oribatula venusta. The extremely short 

 description is as follows : — " Testaeea. Facies 0. calypterae BerL, sed multo 

 maior abdomineque magis rotundato. Organa pseudostigm. bene clavata. 

 Pteromorpharum rudimenta ut in 0. calyptera. Ad 600 fx long. ; 400 fi lat." 

 (14, p 8). A figure of the dorsal aspect of the animal appears in a subsequent 

 paper ( 10, p. 229, Taf, xx, fig. 70). The species differs from allied forms in 

 the shape of the body, the lamellae, and the pseudostigmatic organs. 



The Irish examples vary but little in size and shape (fig. 33a), the 

 length is about o39ju, and the breadth 341,u, therefore slightly smaller than 

 the Norwegian specimens. The form is broadly ovate, shoulder flaps very 

 pronounced, a little more so than in A", similis, the end of the body is slightly
