PARAPONTELLA. CO 



the rudimentary lower foot- jaw and the comparatively 

 poor setose armature of the upper, the single-branched 

 mandibular palp and the peculiar structure of the 

 maxilla are points of difference which seem to me of 

 generic importance. I have had no opportunity of 

 examining living specimens, and cannot in my spirit- 

 specimens make out eyes of any kind, but I am dis- 

 posed to think that in this matter the species will be 

 found to belong to the subfamily Calaninge rather than 

 to Pontellinas.

Head separate from the thorax and ending in a 

 short forked rostrum. Superior antennas 18-jointed 

 (fig. 3) about as long as the cephalothorax, mode- 

 rately slender, and (except on the right side in the 

 male) of nearly equal thickness throughout, the first 

 joint large, the next six small, the rest from twice to 

 thrice as long as broad, except the last which is about 

 four times as long as broad and bears a finger-like 

 apical process (longer in the male than in the female) 

 and about seven long apical setge ; each joint bears a 

 few short hairs, but the first, eleventh, thirteenth, and 

 sixteenth have each one larger apical seta; the joints 

 of the right male antennas (fig. 2) are greatly reduced in 

 number by coalescence, the last three being very long
