species may have contributed to what has been published as the 

 life-history of E. extendens. 



The species has been found in England, near London, and at 

 Folkestone Warren, and in Ireland. It is well distributed over 

 Europe, and has also been recorded from Palestine, Egypt and 

 Portuguese E. Africa.

This species was found originally in Palestine, and was recorded 

 by Koenike as E. extendens. Two years later he gave it the name by 

 which it is now known. The intercapsular bridge is distinguished 

 by its extraordinary width, amounting, in the case of a specimen 

 4:"5 mm. in length, to 0*25 mm. The length of the bridge may be 

 about half the length of the capsules. On the inner side of each 

 capsule there is a tactile hair, and between that again and the 

 median point, the anterior margin of the bridge develops on 

 each side into a process. In a marked degree "^.he capsules and 

 bridge suggest the outline of a dumbbell. 



The first two segments of the palpi are much wider at the 

 distal than at the proximal extremity, the extensor surface of 

 each being about twice the length of the flexor surface. The third 

 and fourth segments are nearly parallel throughout. The distal 

 flexor surface of the third segment tends, though indistinctly, to 

 bulge out and bears a number of strong bristles, some of which 

 are coarsely pectinate. The inner surface of the fourth segment 

 has a number of irregularly disposed bristles, of which some are 

 pectinate. The fifth segment tapers towards the distal extremity, 

 and ends in a cluster of bristles, so much blimted as to suggest 

 that their extremities have been broken ofi. 



The capitulum is roughly rectangular in outline, the lateral 

 and posterior margins being nearly straight, though the anterior 

 margin arches well forward. The median line of the outer 

 surface is very distinctly keeled. The anterior processes are longer 

 and more slender than those of extendens. The posterior pro- 

 cesses are very short and bend downwards. The mouth area is 

 unusually large, forming a transverse ellipse which is surrounded 

 by a narrow strip rendered conspicuous by its very large pores.
