 Notaspis cuspidatus (Michael.) 



The shape varies from oval to broad-oval, and my specimens 

 have unvariably a pectinated hair, standing upon the distal end of 

 the fectopedia 1 This hair is curved toward the top of the rostrum. 



Scutovertex ve latus (Michael). 



Michael calls this species Tegeocranus velakis. I consider it , 

 however, as a true Scutovertex, Istly because the «céphalothorax 

 and abdomen are joined by a central projection of the former, or 

 otherwise !> , 2dly because the animal's habitus is not at all that 

 of a Tegeocranus, but of a Scutovertex , or, at least, of a Carabodes , 

 3dly because the lamellae and their cusps have perfectly the same 

 shape as those of Scutovertex caelatus Berl. and Scutovertex sculptus 

 Michael. This is so striking, that we may make a group of them 

 within the genus Scutovertex. 



I therefore propose to change the « key » of Scutovertex on p. 29 



of « Das Tierreich , Oribatidae » as follows : 



, Lam. broad , horizontal ; C. lam. long , large , 



\ with rounded distal ends — 2. 

 1. / 



Lam. narrow , or only thickened bars , or 



I'idges, or scarcely visible — 4 



^ Ung. trid S. SCUlptus. 



( Ung. monod. — 3.
