482 ADDITIONAL NOTES ON PERIPATUS LEUCKARTI, 



them much contracted and with the feet bent ventrally, making 

 satisfactory investigation difficult. He was however able to make 

 out in the male the presence of "a rounded white papilla on 

 the ventral face of the fifteenth leg, on each side of the genital 

 opening." 



Mr. Dendy out of thirteen specimens met with only one male, 

 not a very satisfactory specimen, and he also speaks of the presence 

 of a small white papilla on the venti'al surface of each leg of the 

 last pair. 



On examining the specimens now in i-eview it soon became pro- 

 bable that the collection contained an unusually large proportion 

 of males, though what I took to be such had not precisely the 

 characters mentioned by Sedgwick and Dendy ; that is to say I 

 was able to pick out a number of specimens, all of them small, 

 with not prominent genital papillae, and with papillae, generally 

 M'hitish, on the ventral surface of some or all of the legs, with the 

 exception of those of the first pair, but not merely on the legs of 

 the last pair only. And this state of things I found to obtain not 

 only in specimens from Mt. Kosciusko and Dunoon, but also in 

 three specimens from Queensland lent me by Dr. Haswell who 

 received them from Mr. Tryon, and in one from Illawarra given 

 me by Mr. A. G. Hamilton. The pre.sence or absence of papillae 

 seems to be a matter of little importance. In some specimens 

 they are recognisable on all the legs with the exception of those of 

 the first pair ; in others only on some of these ; the first two pairs 

 (on the second and third pairs of legs) are generally quite con- 

 spicuous, as also are those on the posterior seven or eight pairs of 

 legs with the exception of the last pair ; the legs on which they 

 most frequently appear to be wanting or on which it is most difficult 

 to identify papillae or pores, if present, are the 4th and 5th and 

 one or two succeeding pairs, and the 1.5th pair; sometimes they 

 are not equally conspicuous on both legs of the same pair ; in the 

 male of group (d) from Mt. Kosciusko unusually large papillae are 

 present on each leg of the posterior nine pairs except the first and 

 last leg but one on one side of the body on which they are rela-
