J?c-marks. —There is considerable difference between male and female 

 in these lots with regard to the character and number of spine-bearing pro- 

 jections, but they are so similar in other respects that I think there can 

 be very httle doubt about their being the same species. 



No egg-masses were found upon the ovigera of the male, but ova of 

 various sizes could be seen in the third coxal and femoral joints of the 

 legs of the females. 



The peculiar structure of the ovigera of the male, the last three joints 

 being articulated to the seventh at an angle, reminds one of the somewhat 

 similar condition in the male of Discoarachne [cf. Cole, :oi^ Taf. 13, fig. 

 4), and strongly suggests the close relationship, and probable synonymy, 

 of these two genera. 



The character of the spines on the ovigera could not be well made 

 out ; at a medium magnification they appeared to be simple, but with a 

 "i^ oil immersion objective the two on the tenth joint of the female 

 showed fine lines indicating a denticulate margin. On the ninth joint of 

 the same leg was a peculiar, flat, double-notched spine, shown in figure 

 3, plate XXIII. 



The single female specimen of Lot 26 was almost completely covered 

 with small stalked protozoa ( Vagmicolina). 



Genus Clotenia Dohm ('81). 



Trunk very short and broad, the lateral processes short and closely 

 crowded, so that the body is concentrated and disciform ; trunk seg- 

 mentation suppressed. Eye tubercle set well back on first trunk segment ; 

 caudal segment well forward and pointed upward, so that the distance 

 between it and the eye tubercle is short. Chelifori i -jointed; palpi 4- 

 jointed ; ovigera present in both sexes, lo-jointed. Legs rather stout; 

 openings of the male genital ducts in the usual position on the second, 

 third, and fourth pairs of legs (Dohm) ; without genital protuberances. 



Remarks. — The greatly concentrated body, with the consequent near- 

 ness of the caudal segment to the eye tubercle, which is set well back, 

 and the 4-jointed palpi, would seem to be sufficient to distinguish 

 this genus, though it is certainly very closely related to Tanystylum. 

 Dohm makes a strong point of the fact that the genital openings of the 

 male occur on the three posterior pairs of legs. Although there can be 

 no doubt of the close afl[inity of the specimen from California to Dohrn's 

 Clotenia coiiirostris, I was unable to confirm this point. The openings 

 could be seen on the third and fourth pairs of legs, but on the second 

 pair I was unable to find them.
