Clare Inland Survey — Acarinida.

The palps (PI. III., fig. 32 a) are extremely small, being only about half as 

 long as in average examples of U. crassipes. The second segment is rather 

 strongly arched dorsally, furnished on its inner side with two small stout 

 spines. The third segment carries two long and rather stout bristles, one 

 situated distally, the other springing from near the middle of the outer 

 surface, and reaching to near the end of the fourth segment. This outside 

 spine is very much shorter in IT. crassipes. Both of these bristles are 

 decidedly bent towards their extremities, and under a high magnification 

 (x 386) they are seen to be excessively finely pectinated. 



The fourth segment is short and stout in comparison with U. crassipes, and 

 the three chitinous pegs (length of longest, '085 mm.) appear rather close 

 together in side view ; near the base of the segment on the outer side is a very 

 fine long hair. 



The form of the body is oval, except at the posterior end, where it is 

 flattened, or slightly sinuate. The length of the female is '89, and the 

 breadth - 69 mm. The colouring is much as in U. crassipes. Some of the 

 female specimens, collected in the month of June, contained numerous 

 eggs, the average diameter of which is about '143 mm. 



The capitulum has the sides remarkably straight ; and overlying the basal 

 part in some specimens is a thin plate of chitin forming a bridge between the 

 first pair of epimera. The latter meet or are separated by a slight distance 

 on the middle line of the body. The sub-cutaneous processes (PI. III., 

 fig. 32 c) of the second pair vary a little in length, but they appear to be 

 longer and more slender than in U. crassipes. 



The genital area closely resembles that of U. crassipes. A figure of that 

 of the male will be found on Plate III., 32 b. 



The male of this species is a little smaller than the female. The measure- 

 ments are as follows : —
