the Eophrynidge or Anthracomartidee. The two species here 

 assigned to it resemble each other, and differ from the known forms 

 of the other genera in certain characters of which the value cannot 

 accurately be assessed on account of scarcity of material wherewith 

 to test their constancy. Pending the discovery of this desirable 

 addition to our knowledge, it is a matter of indifference whether 

 we classify Brachypyge with the Anthracomartidee or Eophrynidaa.

 with lettering as in Fig. 1, G, witli the additiou of imj}-, marking the impression 

 of the coxa of the sixth appendage. 



- Dorsal ■siew of Anthraconiartus palatinus, after Ammon. car. carapace ; 

 0. eyes. Lettering of the opisthosoma as in Fig. 1, A and C, the segments 

 marked 'dtc/., 10 ty., and 9 st. indicated by dotted lines to show their position 

 beneath the eighth segment with its lateral movable and median immovable 

 lamina? (8 ty.). 

 C, D.— Dorsal and ventral views of posterior end of opisthosoma of Anthracomartus 

 voikelianus, Karsch (after Haase). Lettering as in the foregoing figui-es. 



The following table will perhaps, as well as another, represent 

 the affinities of the genera : — 



a. Carapace with its dorsal area flattish or evenly convex from side to side, un- 

 (fifferentiated into a median elevated and a lateral horizontal area, and without 

 strongly marked median and lateral muscular impressions. 



Fam. Anthracomabtid^. 

 a}. Free edges of the lateral tergal laminaj of the opisthosoma concave, Avith 



projecting spiniform angles Braehypyye, Woodw. 



51. Free edges of the lateral tergal laminae evenly convex, forming a continuous 



curve Anthracomartus, Karsch. 



h. Carapace with its dorsal surface differentiated into a median elevated area and 

 a horizontal lateral area ; the median and lateral muscular impressions deep ; 

 edges of tergal lamina? of opisthosoma convex as in Anthracojnartus, but the 

 posterior angles of the seventh and eighth spiniform . . . Fara. Eophrynid^.
