ANTHURIDAE 



Bathura, n. g. 



Diagnosis: Eyeless. Dorsal pits and paired statocysts present. Per- 

 aeopod one subchelate, enlarged palm with proximal low curved tooth 

 with many lateral setae. Hand of peraeopod four forming strait joint 

 with propodus; carpus slightly underlying propodus on peraeopods five 

 to seven. Carpus about one-half length of propodus on peraeopods four 

 to seven. Peraeopods four to seven laterally compressed. Pleonal seg- 

 ments distinct. Endopod of uropod longer than telson. Telson with 

 pair of statocysts, pointed and with marginal row of several apical setae. 

 Two ridges on telson with medial groove continuous with medial groove 

 of pleonal segment six. Lateral edges of pleonal segments visible in 

 dorsal view. Both first and second antennae with few flagellar articles. 

 Bathura is most like Ananthura, K. H. Barnard (1925), from which it 

 differs in general pattern of peraeopodal hand with a tooth on palm, 

 and characteristic pattern of setae on apex of telson and uropodal rami, 

 without any conspicuous serrulations on outer margins on endopod. 

 The type species is B. luna. 



Bathura luna, n. sp.

 dorsal pits on segments four to seven with two lateral pits on seven. 

 Medial rostral projection not extending as far forward as anterolateral 

 projection. First peraeonal segment about two-thirds as long as fifth;
