ASPTDTOTUS PERSE JE. 113 



to quote Prof. Comstock's original diagnosis of the 

 female. 



He says : " The colour of the female is orange. The 

 body is nearly as wide as long. The last segment pre- 

 sents the following characters : there are four groups of 

 ^spinnerets; the anterior laterals consist of from ten 

 to twelve, and the posterior laterals of about eight. 



" There are three pairs of well-developed lobes 

 present ; each lobe is wider than long ; the first lobe of 

 each side is the smallest, the third the largest; the 

 second is usually notched ; the third is serrate. 



" The posterior half of the lateral margin of tlie 

 segment appears to be of the same structure as the 

 lobes ; it is serrate, and usually more or less deeply 

 notched four or five times. 



" The body- wall is furnished with seven thickenings 

 on each side of the meson. These thickenings are long, 

 somewhat club-shaped, the anterior part being enlarged 

 and rounded. There is one terminating at the base of 

 each margin of each lobe. Those ending at the base of 

 the lateral margins of the lobes are much longer than 

 the others. The seventh thickening terminates be- 

 tween the second and third lobes, and is narrow and 

 inconspicuous. 



" The plates are small, inconspicuous, and irregularly 

 toothed. There are two between each pair of lobes, and 

 between the third lobe of each side and the posterior 

 lobe of the thickened lateral margin. ******* 



" On the ventral side there are four pairs of spines, 

 there being a spine at the base of the lateral margin of 

 each lobe, and one at the anterior end of the thickened 

 part of the lateral margin of the segment. On the 

 dorsal side there are only three pairs of spines, there 

 being none on the first lobes. Those of the second 

 and third lobes are situated near the middle of the 

 bases of the lobes ; the third spine is nearly opposite 

 the fourth spine of the ventral surface."
