ARACHNIDES ARANEIDES TUBITELARLE. 61 



family, which are not numerous, are almost exclusively confined to the 

 European fauna (especially the Mediterranean district) and to South Amer- 

 ica. (November, 1881.) 



Gourret has recently described a species of this family from Aix, the 

 first known from the European rocks; it is referred to an extinct genus, 

 1 'rod ysdera. (October, 1889.) 



SEGESTRIA Latreille. 



A single species is referable to this- genus, and with little doubt, as it 

 bears a striking resemblance to the living S. senocnlata (Linn.) of Europe. 

 Eight species of the genus have been found in the European Tertiaries, all 

 from the amber of the Ualtir, and two others are reported as known to 

 Menge t'loin the Minie source. All the described amber species are smaller 

 than the American species, and have longer legs and more elongated cepha- 

 lothorax, being evidently more nearly related to one another than to the 

 American form. The living species of the genus are found in southern 

 Europe, northern Africa, and Chili, with a single one in New Zealand. A 

 warm temperate climate is therefore indicated. (November, 1881.) 



SEGESTRIA SECESSA. 

 PI. 11, Fig. L'S (9). 



Fenitilr. Cephalothorax short, rounded ovate, about one-fourth longer 

 than broad, with no distinction of cephalic and thoracic, areas, the front 

 broadly rounded, obscure, with no trace of eyes. Mandibles very stout, 

 tapering, rounded at the tip, half as long again as broad, half as long as 

 the cephalothorax, and together as broad at base as the front of the 

 cephalothorax. Palpi slender, longer than the cephalothorax. Abdomen 

 rather long ovate, about twice as long as the cephalothorax, and a little 

 broader, broadest in the middle, tapering only a little toward the base, 

 considerably toward the acuminate tip. Whole body of an almost uni- 

 formly dark color. Legs subequal, moderately long, and pretty slender, 

 tapering a little only, the tibia: and tarsi furnished above with lateral rows 

 of very long tapering spines which do not diverge, but lie along the sides 

 base to tip. 



Length of body, 9.5 mm ; cephalothorax, 2.75 mm ; abdomen, 5.25 mm ; 

 breadth of cephalothorax, 2.25"""; abdomen, 2.65 mra ; length of cheliceres,
