 true impressions, * * * " Mr. Banks also informs me that it is. 

 from Santa Rosa Island (near Santa Barbara), not Santa Rosa, 

 Sonoma County. The type of A. atomarious is, unfortunately for 

 me, in France, and the specific type locality not recorded. Until 

 I have collected in many other portions of California, and satisfied 

 myself that a genus exists, in this State, having the sternal im- 

 pressions, and other characters, ascribed to Aptostichus, I do not 

 feel justified in proposing a new genus to include my material now 

 assigned to that genus. 



Aptostichus atomarius Simon, loc. cit. 



I have two specimens, large females 25 and 27 mm. long, 

 respectively, taken along the Sur County-road, near Carmel, 

 south of Monterey, December, 1907. These show" some varia- 

 tions from the description of A. atomarius, but agree with that 

 form too well, in w^hat seem to me to be the more reliable specific 

 characters, for me to try to establish a new species upon this 

 limited material. A sufficient series, however, including many 

 ages and sizes, may lead to other conclusions later on. I searched 

 several hours for additional specimens, on the day these two were 

 found, and returned several days later, going over the same and 

 adjacent ground, but all in vain. 



Plate XIII, fig. 32, shows the sternal and labial characters 

 as represented in these two individuals, excepting that, in the 

 one drawn, the labium has three spinules, Avhile in the other it is 

 unarmed. The anterior two of the six impressions are quite 

 distinct. The eye-tuber is much higher than in the next species, 

 is very prominent (Plate XIV, figs. 30 and 31), but is not men- 

 tioned by Simon. The abdominal markings are of the pattern 

 shown in Plate XIII, fig. 27. The pale appressed pubescence 

 of the cephalothorax, as well as the shape, thoracic-pit, etc., is 

 well shown in Plate XVI, fig. 3, and needs no lens for its dis- 

 covery. The armature of the pedipalps and legs show some inter- 

 esting variations: Tarsi P with two sub-basal spines, one indi- 

 vidual having also a small sub-apical spine, externally; tibiae 

 P with three apical spines, each lacking one of the four other 

 spines to be expected, the missing spines not corresponding as to 

 position. Tarsi I and II unarmed, considerably shorter than 

 metatarsi; metatarsi I with one to three small apical spines and 

 one to three other short stout spines, not constant in position;
