740) NEW YORK STATE MUSEUM 
Maypacius vittiger Simon is an African species and has 
been reexamined at my request by M. Louis Fage of the Paris 
Museum. In this species there are but two teeth on the lower 
margin of the furrow of the chelicera and the area of the four 
median eyes is longer than wide. M. floridanus therefore, can 
not be regarded as congeneric with Maypacius vittiger 
and is transferred to the genus Thanatidius. 
Habits. Nothing is known of the habits of this species except 
that the female is mature in June in the Okefinokee swamp, Georgia. 
Distribution. *Florida, *Billy’s island, Okefinokee swamp, Ga.; 
*Holt, Tuscaloosa county, *Epes, Sumter county, Ala.; *Baton 
Rouge, La. 
PELOPATIS nov. gen. 
Generic characters. Cephalothorax considerably longer than 
broad, depressed. Eyes in four rows; total area of eyes slightly 
broader than long; line of anterior lateral eyes (first row) at least 
twice as wide as line of posterior median eyes (third row) ; almost 
as wide as line of posterior lateral eyes (fourth row) pl. 4, fig. 2; 
area outlined by four anterior eyes almost 3 times as broad an- 
teriorly as long. Median ocular area very slightly broader pos- 
teriorly than long or equal. Abdomen long and slender with a 
median, basal, lanceolate spot, on each side of which near the mid- 
dle of its length, is a small, black spot. Lower margin of the fur- 
row of the chelicera with three teeth (pl. 4, fig. 4). Legs 1-4-2-3; 
tibiae of first and second legs beneath with 2-2-2-2-2 spines, four 
pairs extremely long and overlapping; apical pair reduced and some- 
times missing; metatarsi of first and second legs beneath with 2-2-2-2 
spines; apical pair short. Sternum longer than broad, produced

1 F, Pickard—Cambridge (Proc. Zool. Soc. London, 1¢03) questioned the 
identity of Thanatidius in note 2, p. 153, as follows: “One can not be quite 
certain that Thanatidius has been correctly identified.’ On page 156, the 
description of the eyes of Thanatidius spinipes makes it appear that 
the anterior row is much wider than the posterior. The description refers to 
the figure (pl. 14, fig. 10) which is apparently reversed on, the plate. When 
turned right side up, the eyes appear as they are in Pelopatis undulata 
(Keyserling ).
