are narrow, acute, curved, and are separated at their bases. There are no outer or 

 inner barbs on the claws. 



Variety 2. Smaller, length 190 M . Seta a not seen (only dead skins were 

 examined). The three lateral spines (b is absent) are nearly equal, of 30 to 40 M. 

 They are usually strongly curved, and they bear few (three or four) large spinules, 

 which are also curved. The dorsal spines over c and d are of similar length to the 

 lateral spines. They are broad and flat, and are irregularly serrate or merely erose 

 on the margins. The dots on the plates are like those of variety 1. There is no 

 note of the crossing of the paired plates by a plain band. Fringe and claws were 

 not seen. 



The middle lobe of the trefoil of the lumbar plate seems marked off from the 

 anterior portion by a narrow band, interrupting the granules. This may be merely 

 optical, as it often happens, when this part of the plate forms a panel set at an angle 

 to the rest of the plate, that the thickness of the plate is seen in optical section, 

 marked by two parallel lines. 



Habitat. Variety 1 common in the Blue Mountains and in Queensland ; variety 

 2 Queensland. 



The Australian varieties differ from the type in having the dorsal processes also 

 serrate. Variety 1 is nearer the type ; variety 2 lacks spine b. 



Echiniscus blumi, Eichters (27) (Plate XVI. Fig. 14) 



Habitat. Australian Alps, several examples. 



Agreeing in the main with Eichters' figure, there are some small differences of no 

 great importance. I saw no third median plate, but that may often be hidden by 

 :he pair in front. The dots, which appear to be granules, are smaller and closer. 

 Che lumbar plate is not divided right across, as in Eichters' figure, but simply divided 

 by two slits into a trefoil. In this respect I believe Professor Eichters now agrees 

 with my interpretation. 



Some of the setae in the example figured have little curved branches, which I 

 have seen in no other species except an undescribed Antarctic one. The straight 

 spines on the outer claws of the fourth legs vary from one to three in number, as I 

 have previously observed in E. granulatus. The largest example measured 400 M in 

 length, exclusive of the fourth legs. 



Echiniscus oihonnce, Eichters ? (27) (Plate XVII. Fig. 21) 



There are several points of difference from Eichters' type which render this 

 identification more than doubtful. The lateral process c is reduced to a long spine : 

 the dorsal process over d is elongated into a sharp spine of moderate length ; the 

 spicules at the bases of b, c, d, and e, were not observed. In the aggregate these 

 characters are of some weight, but the most important one (the lack of spicules) is
