genus in our country, the S. marinus Banks, that occurs on 

 the surface of boulders between tide-marks along the Long 

 Island shore. 5*. marinus is usually found in small depres- 

 sions of the stone, but forms no cavities ; and when the tide is 

 out one can find a few wandering over the rock. Four species 

 of Scutovertex are known in England, one was found in moss ; 

 one on lichen near the seashore, and two on algae in fresh- 

 water pools near the seashore. Michael has described a spe- 

 cies as taken from marine algae at Terra del Fuego. 

 The new species I describe as follows : 



Scutovertex petrophagus n. sp. 



Rather uniform dark brown, a pale spot on middle of base of abdomen 

 above. Body moderately elongate, roughened above ; median area of 

 cephalothorax with transverse ridges. Pseudostigmatic organs short, 



clavate. A ribbed 

 lamella-like area 

 around base of ab- 

 domen. Abdomen 

 above with scatter- 

 ed rugosities and 3 

 more or less defi- 

 nite stripes of inter 

 laced ridges; at api- 

 cal margin with 4 

 short, subequal stiff 

 ss /1 bristles each side

The legs are rather 



long and heavy, the femora obliquely 

 roughened above near tips, and also on 

 the trochanters ; tarsi very short, and 

 more hairy than other joints, but one claw 

 to each leg. Venter finely and irregularly

rugose, the coverings of the apertures being longitudinally rugose. The 

 genital opening is about as broad as long, and scarcely its length in front 

 of the larger and more elongate anal opening. The immature stages 

 have a transversely corrugate dorsum. Length 4 mm. 



Inhabits cavities in the surface of wet rock. Traghanic 

 Falls, near Ithaca, N. Y. This genus is best separated from 

 Carabodes by the fact that the tibiae of legs are not pedicellate.
