114 CHAELES D. SOAR AND W. WILLIAMSON ON 



The palpi are about 0*90 mm. in length. The distal portion of 

 the flexor surface of the third segment bulges out, and is furnished 

 with about a dozen spines, of which three or four are slightly 

 pectinate. The flexor surface of the fourth segment has about 

 five spines on the outer edge. Inwards there are five spines and 

 five pectinate bristles, of which four are distal. The fifth segment 

 has four short bristles at the end, and on each side there are two 

 short spines. 



The anterior edge of the capitulum is emarginate. The portion 

 of the capitulum lying posterior to the almost circular mouth is 

 covered with numerous angular pores. The antero-lateral pro- 

 cesses are of normal form and pass obliquely into the body. The 

 postero-lateral processes are not very thick, but they are broad- 

 ened 'at the ends. The pharynx narrows slightly in front of the 

 pharyngeal ridge, but it is well rounded posteriorly. 



E. rimosa has been found at Lowestoft and at Woking and 

 Epping Forest. It has also been recorded from Switzerland, 

 Kussia, Italy, Finland, Austria-Hungary and Germany, as well as 

 from Algiers. The life-history is unknown.

The intercapsular bridge is about the same width as that 

 of E. extendens and about half the length of the capsules 

 themselves. The anterior margin is wavy, while the posterior 

 is almost straight. Nearer to the anterior margin, and about 

 equidistant from each other and from the eye capsules, there are 

 two moderately long bristles. The anterior eye lenses are each on a 

 stalk, and the posterior lenses are of an elongate ellipsoidal form. 



The palpi are about 0*8 mm. long. The flexor surface of the 

 third segment passes gradually into a strongly developed anterior 

 prominence, having about a dozen spine-like bristles on it. The 

 flexor siirface of the fourth segment bulges out in its anterior 

 portion, and has an inner row of three bristles and an outer row 

 of six or seven, and with the latter there is to be noted a short 

 curved bristle set upon a small papilla and two small pectinate 

 hairs near the two anterior bristles. The anterior bristle of the 

 inner row has numerous small pectinate hairs about it. 



The capitulum agrees closely with that of E. mulleri Koen.
