SOLPUGA CERVINA, 11. sp. 



(Figs. 21, 21a.) 



Flagellum. Basal enlargement high, the upper and hinder borders 

 continuously convex. Whole shaft procurrent,* not at all recurved, 

 broad, strongly flattened from above, curving gently outwards and 

 very slightly upwards, thickened towards the apex and terminating 

 in a short, sharp, strongly curved spur, which is directed outwards 

 and upwards. On the outer edge of the thickened part is a strong, 

 obtuse, lobe-like process directed backwards and upwards; nearly 

 opposite this lobe and slightly distal to it on the inner edge is a 

 curved filiform process, exceeding the apical spur in length and 

 minutely serrated along the outer edge ; apex of flagellum situated 

 over or a little anterior to the apex of upper jaw. 



Upper jaw of mandibles in $ with the first two teeth strong, 

 hooked, and rather remote from the apex of the jaw, followed after 

 a short interval by two smaller teeth, of which the anterior is very 

 minute ; fifth or last tooth of the single series strong and hooked. 

 Terminal fang long and slender, with distinct sigmoid flexure, strongly 

 depressed at the base (which bears the two hooked teeth), then 

 curving gently upwards, and then again downwards and strongly 

 outwards at the apex ; its surface rather convex above, the inner 

 side not dilated, provided with a minute tooth. Lower jaw as usual 

 (in one jaw the first tooth is not larger than the second), the upper 

 surface not sulcate, nor keeled laterally alongside the teeth. 



$ . Between the second and third large tooth of the upper jaw 

 of the mandibles are two small ones, the anterior of which is very 

 minute. Lower jaw with one small tooth between the two large 

 ones. First segment of the abdominal sterna not produced behind 

 at the median angles. 



* This species affords an excellent illustration of the alteration in position 

 which the flagellum often undergoes in the process of drying. If a spirit specimen 

 he exposed to the air for a short time, the flagellum curls up until its distal half 

 is quite curved backwards. On relaxing a dry specimen the organ appears to 

 return to its original position.
