F al se legs weak, 10-jointed, without denticulated spines; last 

 four joints strongly curved; the 10 th bears a very small claw. 



Legs slender; terminal claw strong, without auxiliary claws. 



Lateral casca of the intestine penetrating as far as the 

 fourth joiut of the legs. 



Eggs in the body and its lateral processes, but only in the 

 proxiraal two joints of the legs. 



PIPETTA WEBERI n. sp. 



The body of this species is elongate and slender, and every- 

 where of the sarue breadth, only the abdomen being thinner. 

 The segments are divided from each other by sharply defined 

 sutures. The cephalic segment is short and bears the oculiferous 

 tubercle rather in the centre. The 2 d , 3 d and 4 th segments are 

 of about equal length but much longer than the first; the abdo- 

 men is placed horizontally and has nearly half the length of the 

 trunk. The lateral processes are cylindric and have a width equal 

 to that of the trunk; they are longer than the segments, with 

 the exception of the last, which is the shortest and measures 

 only one third of the second one. 



The oculiferous tubercle is comparatively low, obtusely rounded 

 and directed a little forwards, without a tracé of eyes. 



The proboscis is exceedingly slender, */ 3 longer than the trunk. 

 lts posterior part is slightly swollen, spool-shaped, but not wider 

 than the trunk; it contains the so-called »Reuse" with strong 

 muscles. The anterior 2 / 3 form a cylindric tube, externally with 

 distiuct transverse chitinous rings. The triangular buccal orifice 

 is very small, the lips beiug grown together. In this anterior 

 part I have not been able to detect a tracé of muscular structures, 

 neither at the interior tube, nor at the fused lips. 



The chelifori are absent. 



The palpi are slender and even a little longer than the pro- 

 boscis. The joints are of very different size; the first, ovoid, is 

 small; the second very long and somewhat tumeficated at the 

 extremity; the third is short, like the first; the fourth about the
