The type of Pycnoctenus, L. K., will be the single species 

 described at the time of foundlnc; the genus, P. 7'ohustus, L. K. 

 For the same reason Ailus curtus, Cambr., remains as the 

 type of Nihts, Cambr. L. monastoi'des, Cb., was the single 

 species originally assigned to Labdacus, Cambr., while Cyclo- 

 ctenus Jlaviccps, L. K., is, for the same reason, the type of 

 Cycloctenus, L. Koch. Stenoctenus gracilis^ Keys., is also on 

 this account the type of Stenoctenus^ Keys. A. vulpes, Bertk., 

 for the same reason, is the type ol Ancyclometesj Bertk. 



]\J. Simon has selected T. Jimhriatus (Walck.), sub Ctenus^ 

 as the type of [Titurius) Jlialassius^ Sim. V. hidens, Sim., 

 and V. puJchripes, Sim., remain with an undisputed right to 

 be regarded as the types of Vulsor, Sim., and Vir-idasius, 

 Sim., respectively. Dolopoeus cinctus, Thor., is alone also as 

 the type of Dolopoeus, Thor. P. maronicus (Tacz.), sub 

 Senoculus, is the type of Platyctenus, Keys., a name substi- 

 tuted, on the ground of inappropriateness, for Senoculus, 

 Tacz.

1872. Senoculus, Tacz. — A name given to a spider with a 

 Ctenoid eye-formula, supposed by Karsch to be six-eyed, 

 whereas in reality the lateral anterior eyes are present,
