in the other, somewhat larger, one and a half diameters apart. In 

 the former also the rear side-eyes are nearer together than the 

 frout side, and iu the other drawing both distances are the same. 

 The first is from above, the second from in front. M. H. Lucas 

 in a long paper on the genus (loc. rif.), in 1865, saya that the front 

 middle eyes are close together ; he gives a drawing in which they 

 are small and about a diameter apart. His specimen was pur- 

 chased by the Paris Museum in 18-59, and came from 'lea environs 

 de Melbourne ' ; he was able to compare it with the original type- 

 specimen, then b'U years old ; still his identification should be 

 correct. It was 20 mm. long — whether including mandibles or 

 not does not appear. It is to be hoped some fresh specimens may 

 be forthcoming from Melbourne or Sydney. 



In the British Museum are two specimens from Hunter River, 

 N.S.W., and Western Australia labelled E. occatoriurn, females 

 also, old dried specimens ; but they are different from one another, 

 and do not agree with M. Lucas's description. 



In these the rear row of eyes is shorter than the front. The 

 two front middle are small, about three diameters apart, but stand 

 on larger round, slightly raised bases, which may or may not 

 have been originally part of the eyes, but in the dried state are 

 now clearly separable from the seeing part. This probably 

 accounts for the discrepancies above mentioned. The side-eyes 

 are all slightly raised. 



The colour is a uniform rich dark brown, the mandibles black- 

 brown, and the cephalothorax smooth and shiny. 



In the largest there are 11 teeth on the inner margin of the 

 falx-sheath, 9 on the outer, and about 13 smaller in two inter- 

 mediate rows. 



On the superior tarsal claws are 2 or 3 rather long pectinations 

 about the middle of the shaft and 1 on the inferior. There are 

 numerous spines on lip and base of maxillae.
