Neither is Lophomma capito Menge '), nor L. mitratum id. 2 ), — of 

 which forms Menge says, "that he should consider them as one spe- 

 cies, if only transition-forms could be found" (Preuss. Spinn., II, p. 

 218) — synonymous "with E. capito Westr. In L. capito Menge 

 the posterior, hemispherical eminence on the male's head is stated 

 to adhere with the whole of its base to the head; in E. capito Westr. 

 that eminence has the form of an egg divided lengthways, and is only 

 attached at one extremity, so that it is separated from the anterior 

 head-eminence by a narrow oblique fissure directed downward and 

 backward. It is then at least double as high as it is broad, and 

 much narrower than the anterior eminence. In L. mitratum, of 

 which I have received a specimen from Niirnberg of Dr. L. Koch, 

 the posterior eminence is almost spherical, and, when viewed from the 

 side, rather more long than high, and almost of the same breadth 

 as the anterior eminence. — Micryph. capito Ohl. 1867 (Aran. d. Prov. 

 Preuss., p. 67) is also another species, and identical with Walcken. 

 hiemalis Blackw. or Erig. coriacea Westr., of which more hereafter. 



In my Eec. crit., loc. cit. , I erroneously introduced the spider 

 here described by Westring, under the name of E. cucullata (C. 

 Koch). Menge is undoubtedly right in identifying Micryphantes 

 cucullatus C. Koch 1836 3 ) with his Lophomma cucidlatum 4 ). From
