1880. Platyctenus, Keys. Verh. z.-b. Wien, xxix. p 338, 

 note. — A name suggested by Keyserling instead oi Seno- 

 culus. The spiders included in this genus and Stenoctenus 

 probably do not belong to the Clubionidas, subfara. Ctenina*, 

 at all. 



1880. Ancylometes, Bertk. — In the absence of the type or 

 any description made from a comparative point of view I 

 hesitate to suggest tiie athnilies of the genus.
