ART. 13. NEW AMERICAX AXD CHINESE SPIDERS CHAMBERLIN. 11 



Locality. — China: Kiiliang. August 26. (N. Gist Gee). One 

 female. 



Type.—C'^^t. No. 86G, U.S.N.M. 



TETKAGNATHA PLENA, new species. 

 Plate 3, fig. 18. 



Female. — This species is obviously smaller than any of the others 

 here described. The coloration is of the usual pattern. 



Both eye rows clearly recurved. The lateral eyes much closer 

 together than the medians. Area of median eyes scarcely narrower 

 in front than behind. 



The sjDecies is most readily distinguished by the characters of the 

 ohelicerae. These are obviously shorter than the cephalothorax. 

 Lower margin of furrow of chelicera armed over its whole length with 

 a series of about twelve teeth, of which the most proximal are much 

 reduced, and in which series there is no pronounced .diastema toward 

 distal end. Dorsal margin of furrow of chelicera with a tooth at 

 distal end followed by a wide diastema proximad of which is a series 

 of seven teeth. No distinct tooth at distal end either above or below.

Length, 6.8 mm. ; tibia and patella I, 6 mm. ; tibia and patella IV, 

 3.2 mm.

TETRAGNATHA RETINENS. new species. 



Plate 3, figs. 19, 20. 



Male. — The type unfortunately lacks the abdomen, but the cheli- 

 cerae and palpal organ furnish means of eas}' distinction from cliens^ 

 to Avhich it seems to be nearest. The dorsal process of the chelicera 

 is less bent forward, more erect, than in the latter species ; it is simi- 

 larly bifid at the tip, but the lower tooth is proportionately smaller. 

 Above the upper margin of the groove two large processes of distinc- 

 tive form, the more mesal of these presenting a wide swelling at base. 

 Along the upper margin of the furrow are eight smaller black teeth, 

 one of these standing apart near the swelling of the process above 

 mentioned, the other seven forming a series in which the teeth de- 

 crease in size caudad. At the distal end beneath a denticle, as in 

 cliens, but mesad and proximad of this, is only one large tooth instead 

 of two. Along the lower margin of the furrow are six small teeth, 

 of which the most proximal stands opposite the second tooth of the 

 dorsal series.
