EcUniscus sp. ? (Plate XVII. Fig. 25) 



A small animal resembling that figured on Plate XVI. Fig. 18, and having the 

 same number of lateral processes, but having also one dorsal seta on each side. The 

 lateral setae are a, c, d, and e. They differ greatly in length. The seta a is 50 /x in 

 length, c is 30 n, d 150 M (equal to the whole length of the body), e 70 /*. The dorsal 

 seta is over c and measures 50 M. 



The plates are marked with obscure dots, the nature of which could not be made 

 out. The fourth legs have a fringe of sharp spines, and the inner claws have 

 decurved barbs of moderate size, which are farther from the base than usual. 

 Colour pink. 



Habitat. Australian Alps, New South Wales, altitude 5000 to 6000 feet. 



This animal has some resemblance to E. oihonnce, but it lacks the process b, and 

 it has c a spine and d a long seta, whereas oihonnce has c the seta and d the spine. 

 It also lacks the lateral spicules of oihonnoe,. 



EcUniscus, sp. ? (Plate XVII. Fig. 22). 



A large animal with two very long setae on each side, in addition to seta a on the 

 head. There are nine plates, V. and VI. united, two pairs and two median. The 

 dots are large circles of uniform size and close together. The lateral setae are a, b, 

 and c ; b and c are about 170 /x in length. Over c there is a dorsal seta also of 

 170 n ; over d there is a flat spine of 25 M in length by 6 to 9 M across the base. 

 An empty skin measured 270 /u in length by 140 M in breadth. 



The fringe has six to eight blunt rounded processes. There are no barbs on any 

 claws. 



This animal may be compared with E. muscicola, Plate, and E. spitsbergensis, 

 Scourfield. Plate's description (23) is very meagre, and takes no account of the 

 fringe, the barbs of the claws, or the surface texture of the plates. The setae are 

 a, b, c, and e, and over c there is a long dorsal seta. Our animal lacks seta e, 

 and has an additional spine over d. 



Eichters (35) adds to Plate's description, noting the nature of the granulation, 

 and that the inner claws are barbed. His description of the granulation fits our 

 animal. When you focus high on the dots they appear as circles with central 

 points ; when you focus deeper they become hexagons. 



Scourfield's description of E. spitsbergensis (45) is better, and he gives a figure. 

 It has four seise, a, b. c, and d ; it has a flat triangular process over d ; the inner 

 claws are barbed, and there is a fringe of rounded processes. 



This Australian animal stands near to both E. muscicola and E. spitsbergensis, 

 from the latter of which it only differs by one pair of setfe and the lack of barbs on 

 the inner claws. 



Habitat. Australian Alps, New South Wales, altitude 5000 to GOOO feet.
