and must hold that if this frontal plate was present in Kreischeria 

 it was also present in EopJirynus ; and, conversely, if it was absent 

 in EopJirynus, as appears to be the case, Haase probably put 

 a wrong interpretation upon the structure he described as a separate 

 * Stirnschild.' In short, I see no reason for dissenting from Scudder's 

 view that the two genera belong to one and the same family. 



Fig. 1. 



A. — Dorsal surface of Eophryjius prestvicii. i-vi, appendages of the prosoma ; car. 

 carapace ; pregen. tg. terguni of pregenital segment ; 1 tg. {gen.) tergum of first 

 or genital segment of opisthosoma ; Itg.-I tg. terga of second, seventh, and 

 intervening segments with movable lateral laminaB ; '^tg. tergum of eighth 

 segment with movable lateral lamina; and immovable posterior median lamina. 



B. — Lateral view of carapace, the anterior extremity to the left, the posterior to the 

 right. 0. ' ocular ' pit on the median lobe. 



C. — Ventral surface, ii-a'i, coxal segments of the post-oral appendages of the prosoma, 

 those of the second pair (palpi) bearing the maxillary process {inx. ) ; pr. st. sternal 

 area of prosoma with median sternal plates and lateral membranous area ; 1 sf. 

 sternal plate of first or genital segment of opisthosoma ; 2 st. ditto of the second 

 segment, mth paired lobes ; 3 st. ditto of tliii-d segment, with median depression 

 and laterally elevated posterior border ; 4 st.~8 st. ditto of the fourth, eighth, and 

 intervening segments, with paked tubercles ; 9 st. ditto of the ninth or pre-anal 

 segment ; 8tg. lower surface of median lamina of tergum of eighth segment ; 

 9 tg. tergal area of ninth segment ; 10 tg. anal operculum or tergal plate of the 

 tenth segment. 



Provisionally, at all events, I think Brachypyge may be allowed 

 to stand as a distinct genus. It has been dropped as a synonym 

 both of Eophrynus and AntJiracoinartus, without the certainty of its 

 identity with either. Indeed, until the structure of the prosoma 

 is known, the genus cannot with assurance be referred either to
