Pallene näher zu stehen, obschon es kleine Palpen führt. Man beachte z.B. die Zeichnung des 

 Ovigers (seine Fig. 7 auf Taf. 54). Leider sind Proboscis und Abdomen dieses Exemplars verloren 

 gegangen. Wir kennen jetzt schon mehrere Pallene- Arten mit rudimentären (bis 4-gliedrigen) 

 Palpen. Die nicht sehr vollständige Beschreibung Haswell's folgt hier : 



The length of the body is about six times its breadth ; the lateral processes are separated 

 by distinct intervals; they are well developed, being rather longer than the breadth of the body, 

 the neck is rather short and stout. [The proboscis and the abdomen are both lost]. The first 

 pair of appendages are rather short, the first Joint short and thick ; the second ovoid and swollen, 

 produced into a long, rather slender, finger. The second pair of appendages are very short, 

 much shorter than the first, the third Joint the longest. The third pair of appendages are well 

 developed; the first three joints are short and thick, the fourth longer, slightly curved; the fifth 

 considerably longer than the third, provided at its extremity with a remarkable process ; the 

 sixth to the tenth joints are nearly equal, the ninth and tenth being the smallest; the last four 

 joints are armed with denticulated spines of which there are five on the seventh, six on the eighth, 

 four on the ninth and five on the tenth ; there is no terminal claw. The last four appendages 

 are nearly of equal length, more than twice the length of the body, stout, and ornamented with 

 a few conical tubercles each capped with a small, simple spine; the first Joint is short and thick, 

 the second more than twice as long, narrow proximally, very stout distally; the third is shorter 

 and has one or two low tubercles; the fourth is more than twice as long as the second and 

 has two prominent conical tubercles at its distal end ; the fifth is rather shorter than the fourth 

 and has two prominent tubercles in its proximal half; the sixth is a good deal longer than the 

 fourth and has two obscure tubercles in its proximal half and a pair at its distal end; the 

 seventh segment is very small and is armed with a few stout spines ; the eighth is strongly 

 bent, its palmar border is deeply concave, and armed with a row of spines of which the proximal 

 five are much shorter than the rest; the large claw is scarcely two-thirds of the length of the 

 eighth Joint; the accessory claws are scarcely half the length of the large claw. 



The length of the body is an eighth of an inch ; of the posterior appendages a third 

 of an inch. 



Farn. Ammotheidae. 

 Subfam. Nymphopsinae. 



Gattung Nymphopsis Haswell (1881). 



Körpersegmente ganz verschwunden, die Beinträger aber nicht verwachsen; ihre Spitzen 

 weit aus einander gerückt. 



Proboscis grosz und dick, unbewegbar. 



Cheliforen schwach, mit zweigliedrigem Schaft und zarter, bisweilen im hohen Alter ganz 

 rudimentärer Schere. 



Palpen 9-gliedrig; zweites und viertes Glied am gröszten, die übrigen kurz. 



Ovigera des Männchens schlank, viertes Glied sehr lang, auch das fünfte und zweite.
