abdomen uniform dark gray above and below. Cephalothorax rather short 

 and broad; posterior eye-row slightly recurved; P. M. E. oval, less than 

 one-half their diameter apart, fully their diameter from the P. S. E.; A. M. E. 

 hardly their diameter apart, much closer to the equal A. S. E. ; sternum 

 nearly oval. Abdomen hardly depressed, twice as long as wide, truncate at 

 base, and with prominent hairs. Legs of moderate length, no spines under 

 tibiae I and II, one under base of those metatarsi, three pairs under tibia IV. 



One specimen from Tepic, Nov., looks like a Prosthesima; 

 related to G. sericata (bicolor Hentz.) , but separated by larger 

 and closer P. M. E. and slightly different epigynum. 



51. Gnaphosa distincta, sp. nov. 



Plate XIII, Fig. 13. 



Length 7-9 mm. Cephalothorax yellowish brown, sometimes more black- 

 ish, showing the usual marks; legs paler; sternum more reddish; abdomen 

 dark gray, sprinkled with many black dots, most numerous toward tip. 

 Cephalothorax rather broad, quite narrow in front, posterior eye-row strongly 

 recurved; P. M. E. hardly their diameter apart, twice as far from the larger 

 P. S. E. ; the anterior row nearly straight; A. M. E. about their diameter 

 apart, much closer to the slightly larger A. S. E. ; sternum but little longer 

 than broad, broadly truncate in front, sides rounded. Legs short, one pair 

 of spines under tibia I at tip, two pairs under metatarsus I ; posterior pairs 

 with many spines, and one above on tibia III. Abdomen once and a half 

 longer than broad, depressed, truncate at base. Epigynum shows two con- 

 verging bodies in front of which is a short pear-shaped body. 



Several examples; San Jose del Cabo and Sierra San 

 Lazaro, Sept. 



52. Gnaphosa (?) abnormis, sp. nov. 



Plate XIII, Fig. 15. 



Length 10 mm. Cephalothorax, legs, mandibles, and sternum uniform 

 dark red-brown; legs paler at tip; cephalothorax somewhat shining; abdo- 

 men light brown above and below. Cephalothorax rather slender, narrowed 

 in front, dorsal groove quite long; mandibles with a plate behind and a striate 

 portion in front of fang; posterior eye-row a little longer than anterior row, 

 barely recurved; P. M. E. round, hardly their diameter apart, farther from 

 the equal P. S. E. ; A. M. E. small, about their diameter apart and closer to 

 the very much larger A. S. E.; sternum once and a fourth longer than broad. 

 Legs of moderate length, no spines under tibiae and metatarsi of anterior 

 pairs; a number on posterior pairs; short, rather scanty scopulas on anterior 

 tarsi and metatarsi. The epigynum shows a long, slender, central piece and 

 behind two rounded humps near together.
