unten her (ieutlicli sichtbares [joint], welches, oben napfiVirmig ausgehöiilt, das 

 dicke kurze Schienenglied aufnimmt und alsdann zwei, fast gleich lange, schlankere 

 den Tarsalgliedern . . . entsprechend. Die zwei Hinterbeine . . ." If the above descrip- 

 tion of the legs is correct, they must be quite similar to that of a Chclifer GeoL with 

 one-jointed tarsus, as the one of Karsch's two tarsal joints must be regarded as the 

 tibia, his tibia as the tibial femoral part and the "längliches" joint, only visible from 

 beneath as the trochanlin. We will consequently be obliged to regard Corosoma 

 Karsch as a Cheliferid without eyes, with the trochantin of the first pair of legs 

 long and tibial part short and with the head even more produced than in Ganjpiis 

 L. K. The genera Garypus L. K. and Olpiiim L. K. are bj' L. Koch characterized in 

 the following manner. Garypus has "Céphalothorax vor den Augen lang ver- 

 schmälert, der verlängerte Theil abwärts gebogen, mit einer Längsfurche. Zwei 

 Paar vom Kopfende weit entfernte Augen. Das bewegliche Zangenglied der Man- 

 dibeln in ein Stielchen endend. Elf durch ein Längslinie halbirte Abdomiual- 

 segmenle" (1873. 23. p. 38). Simon has besides a few characters (1879. 5. p. 45) viz. 

 "une seule strie transverse", "Téguments chagrines mats; pubescence simple". 

 Olpium L. K. is characterized thus (23. p. 33). "Glänzend. Céphalothorax schmal, 

 lang, vor den Augen abgesetzt kurz verschmälert, sonst gleichbreit, ohne Quer- 

 furchen. — Zwei Paar Augen. Das bewegliche Zangenglied der Mandibeln in ein 

 Stielchen endend. Elf Abdominalsegmente". Simon adds (5. p. 49): „pas de stries 

 longitudinales ni transverses" on céphalothorax; "Téguments du corps et des mem- 

 bres très-lisses, brillants; pubescence simple"; "plaques tergales non divisées sur la 

 ligne médiane". Most authors have accepted the two genera in the above circum- 

 scription only with a few modifications f. inst. Tömösvary, Hansen, who observed 

 that the hairs of the Garypus are not all simple, but partly short and obtuse (1884. 

 9. p. 533 and 550), Balzan and Daday, who laid undue stress on the |)resence or 

 absence of the transverse suture. And this division must be regarded as a prac- 

 tical one at least and is perhaps also a natural one, as it is supported by the old 

 characters except a few, as well as by some new ones (cf. below). 



The character found in the presence or absence of the transverse stripes of 

 the céphalothorax has scarcely any generic value, as species of Garypus L. K. have 

 none, one or two, while at least a few species, which in all other respects are 

 more nearly related to Olpium, have a transverse stripe (cf. p. 90). Daday is accor- 

 dingly wrong in referring 01. biareolatum Tom. to Garypus L. K. The character 

 found in the absence or precence of the longitudinal abdominal line is scarcely of 

 great value, as it is often indistinct in Garypus L. K. and often present in species 

 of Olpium L. K. at least in its wider sense (cf. p. 91). The character which is found 

 in the length of the cucuUus and in its shallow longitudinal groove in Garypus 

 L. K. is certainly very valuable, even if the shape of the cucullus in a species like 

 Garypinns n. sp. from Funafuti is alike that of Garypus L. K.; but the distance, 

 which the anterior pair of eyes is removed from front margin, scarcely more than 

 equals their diameter in this species, while it is three or four times longer in
