Ctcni'form Sju'ders of Ceylon, JJurmali, li'C. 335 



"Vulva ox area subtrapozoidi pallide fusca constant!, quae 

 costas (luas longitudinales jiaralk-ias nigras ostendit." 



If this diagnosis fully describes the vulva, its form is quite 

 sinij)lo, and certainly agrees with none of the species before 

 ine from Horneo.

AVithout actually seeing the types, one cannot pronounce 

 on the identity of this sjjecies with certainty. That it is not 

 identical with trahifer, Thor., as Dr. Tiiorcll himself ])ointed 

 out, admits of no doubt, since Thorell's own identitications of 

 tiie latter are before me. At the same time, I have before mc 

 examples of two distinct species from Ceylon in the neigh- 

 bourhood of Tabrobane {^ and ? ). One of these presents 

 a form of vulva similar in general outline to that of Karsch's 

 figure ; but either the drawing is not executed with sufficient 

 minuteness of detail, or it depicts the vulva of a different 

 .species. In either case it would require a new name, and I 

 am rather inclined to expect that it will prove identical with 

 C. ceyhmevsis, sp. n., describe! below. 



Karsch's figure and the vulva of ceylonensis belong to 

 quite a different type from that to which trahifer, ThorelUi, 

 Floiven'f valvukau's, pulvinaluSj &c. belong. The vulva 

 reminds one rather of that of some species of European Lycosa.

Vulva. "Non multum a vulva C, valvuJaris difFert. E lamina 

 magna subtransversa, fortiter elevata, pjene plana, nitida, 

 secundum medium late et leviter impressa, etc." 



I have little doubt that the forms described below as 

 C saraicakensis and Ilosei are quite distinct from either 

 vahularis [cf. PI. IV. fig. 16) or j^uJvinatus, Thor.; though 

 the indistinctly annulated femora and tibite of iii. and iv. are 

 common to the four species, Ilosei, snraioalcensis, ^^uZyiwa^ws 

 (sec. Thor.), and vahularis (sec. Thor.), and indeed to all the 

 eastern forms which have come before me to a greater or less 

 extent, except denticulatus.
