Read December 2nd, 1834. 



Dr. MAXIMILIAN PERTY in his able work on Brazilian Insects has 

 formed two grand divisions of Phalangidce, and has given us the following 

 characters, viz. 



Divisio Ima. Palpis spinosis, pedibus insequalibus posticis et reliquis valde 

 remotis, femoribus incrassatis, abdomine pliJs minusve in cephalothorace 

 occulto. 



Divisio 2da. Palpis muticis, pedibus omnibus subsequalibus aut sequalibus, 

 abdomine nunc occulto nunc libero. 



As it is at first sight evident that the subject of the present paper can 

 belong to neither of these divisions, partaking as it does of the characters of 

 both, I maybe allowed perhaps to suggest the adoption of a third division, viz. 



Divisio 3tia. Palpis spinosis, pedibus insequalibus posticis vald^ elongatis, 

 non k reliquis remotis, abdomine libero. 



By means of this division, tlie genera Cosmelus and Decosoma, Perty, re- 

 main by themselves, and the genus Phalangium is united with DoUclioscelis 

 the subject of the present notice, the characters of which are detailed at 

 length. 



Arachnida. Trachearia (Lamarck). 



Fam. Phalangid^.
