reaches to the fore margin of the abdomen ; each of the other emi- 

 nences has a single, less distinct, stripe of a similar colour ; and on 

 the fore half of the upperside of the abdomen is a central longitudi- 

 nally brown marking which is produced at its hinder end until it 

 meets the stripe on the third eminence ; four red-brown impressed 

 spots form a square (whose fore side is the shortest) about the 

 middle of the upperside. The sides and underparts are yellow-brown ; 

 the spinners are short, compact, and encircled at their base by a 

 yellow-brown corneous-looking fillet or rim. A large round area at 

 the fore part of the underside, including the spiracular plates and 

 the junctional pedicle, are of a coriaceous texture and bright red- 

 brown colour. 



A single example of this distinct and remarkable Spider was con- 

 tained in a collection made for me in Minas Geraes in 1871, by Mr. 

 Henry Rogers. So far as I know, this is the first male of the genus 

 yet described. The genus, indeed, which is closely allied to Stepha- 

 nopis (Cambr.), consists at present of but three species, E. hetero- 

 gaster, Latr., E. spinipes, Bl., and E. quinquegibbosa, all being 

 found in Brazil. The present species cannot be confounded with 

 either of the other two, not only differing in the number of the ab- 

 dominal prominences, but in their form and colour also : these pro- 

 minences are three in E. spinipes, five in E. quinquegibbosa, and 

 seven in E. heterogaster, the last being also of a large size, while the 

 other two are quite small. 



Fam. PODOPHTHALMIDES. 



Gen. PoDOPHTHALMA, CapcUo. 



The examination of the examples described below long ago con- 

 vinced me that the genus Podophthalma is closely allied to Ocyale. 

 This is contrary to the conclusion lately arrived at by M. Simon 

 (Bull. Soc. Zool. de France, 1876, seance du 7 Juillet), who considers 

 Podophthalma to belong to the family Oxyopides. The form of 

 the cephalothorax and maxillse, as well as the position of the eyes, 

 are totally different from those of Oxyopes; there is, however, perhaps 

 some affinity between them ; at any rate there is a certain resemblance 

 in the general form of Podophthalma and Oxyoj)es ; but even in this 

 respect the resemblance between the former and Ocyale is still more 

 close, while in the form of the cephalothorax there is a very striking 

 similarity ; and if in Ocyale the lateral eyes of the anterior row were 

 separated a little more from each other, and seated at the jiromiuent 

 fore corners of the clypeus, this would make the eye-position ex- 

 ceedingly like that of Podophthalma. The species of Ocyale used to 

 be placed in the genus Dolomedes. All arachnologists, 1 believe, now 

 separate them from the latter genus, while still retaining them, next to 

 it, in the family Lycosides. I have myself long since felt the neces- 

 sity for constituting a family Podophthalmides for Podophthalma 

 and one or two other (as I then conceived) allied genera, forming a 

 passage from the Thomisides to the Lycosides through Ocyale. I 

 have recently found reason to doubt the family affinity between
