Notes ox the Species. 



Fibilodina citrina Ehr. 



Examples from the Rocky Mountains, 3000-5000 ft, were 

 quite colourless. 



PMlodina australis Murray. 



Discovered earlier on the same voyage, in Australia. 



PMlodina plena (Bryce). Plate VI. figs, la-le. 



A small variety from Ottawa is figured. With it were associated 

 eggs (fig. lb) of a very unusual form. They resemble those at- 

 tributed to the species by Mr. Bryce in having a series of rounded 

 knobs round the circumference. They are much flattened, and the 

 apparent knobs are really rounded ridges, which are highest on the 

 edge, and die out on to each of the flattened surfaces. 



Philodina sp. ? Plate VI. figs. 2a, 2b. 



A small animal, 250 /x in length, most like P. nemoralis, but 

 smaller and without eyes. The spurs are small and slender, and 

 are usually held nearly parallel. 



Habitat. — Victoria, B.C. ; several. 



Pleuretra brycei (Weber). Plate VI. figs, da, 3b. 



Variety. — Spines on anterior margin of trunk very small ; 

 lateral spines two at each side ; chief dorsal series, ten spines ; 

 second dorsal series, eight ; series on pre-anal segment, four ; no 

 ridge on first foot-segment. 



The chief peculiarities are : the reduction of all the anterior 

 spines ; the second series of eight spicules on the trunk ; the series 

 of four spicules on the rump. The last character is only shared by 

 a New Zealand variety, and a South African species (P. africana). 



Callidina liabita Bryce. 



Besides the type, there was a variety having the lobes of the 

 upper lip more or less widely separated. This variety is now 

 known in many countries. 



Callidina speciosa Murray (32). 



Previously known only in South America — still confined to 

 the Western hemisphere.
