Of this species Thorell remarks, Ann. Mus. Genov. p. 291: 

 — *' Feminam unicara, qute nondum adulta videtur, ad Bhamb 

 cepit Fea. — C. {Leptocteno) valvularis, Van Hass. (Midden 

 Sumatra cet. p. 45, pi. v. fig. 12), valde aftinis est hasc species, 

 colore ventris tamen plane alio facile dignoscenda." — It seems 

 a pity to base a new species on a young female, confessedly 

 so closely allied to another already described form, in a group 

 in which the species rnn so closely together ; for Thorell says 

 of pulvinatus and fangifer that they also are both closely 

 allied to valvularis. Although I have not been able to see 

 the type, there are before me specimens identified by Thorell 

 as C. trahifer, Thor., from Mr. E. W. Gates's coHection 

 from Burmah. These are distinctly different from G. valvu- 

 laris, van Hass., judging by the figure of the vulva of the 

 latter. They are also quite distinct from any of the other
