140 Macteay Memoriat Vouume. 
the posterior pair is nearly transverse. The anterior pair, which are the smaller, are 
situated behind the middle of the intestine; the posterior pair are altogether behind 
the intestine. The cirrus is narrower in proportion to its length than in most of the 
other species, strongly curved, with a distinct, very narrow, curved terminal segment 
apparently devoid of spinules. 
The few specimens of this species which I have seen were obtained, some on the 
outer surface, others in the branchial chambers of Zxg@us fossor, the land crayfish of 
Gippsland. 
9. TEMNOCEPHALA CHILENSIS. 
Temnocephatla chilensts, Blanchard, 1.c. 
The description of this species given by Philippi is not sufficient to enable one 
to distinguish it, as it would apply equally well to at least four kinds which a careful 
examination shows to differ in certain very essential particulars. 
It was found, as already mentioned, on the surface of a species of Zg/ea in Chili. 
The specimens which Monticelli mentions as being in the Zoological Museum in 
Berlin, with the locality Brazil, and the eggs of which he describes, may belong to 
this species or to 7. /heringit. 
10. TemnocerHaLA SEMPERI. 
T. Chilensis, Semper (?), l.e. p. 307. 
T. Sempert, Weber, l.c. p. 26. 
This species has five subequal, slender tentacles, has the anterior testis situated 
nearly exactly opposite the middle of the intestine, and the posterior one nearly 
completely behind the latter; there is a short rounded ejaculatory sac; the cirrus is 
straight or nearly so, and its terminal part, slightly dilated, is armed with numerous 
extremely minute spinules. 
It seems to me extremely unlikely that the species described by Semper and 
found by him on various fresh-water crabs in the Philippines is the same as that 
found by Weber in Sumatra, Java and Celebes; but though there are differences 
between Semper’s figures and Weber’s, particularly those of the cirrus, there is not 
enough evidence to decide the point.
