REPORT OX THE BRACHYURA. 273 



79. Lophopanopeus lobipes (A. Milne Edwards). 



Bahama Banks: station 46. off Key West, shallow water. 



Genus Eupanopeus nom. nov. 

 (=Panopeus Milne Edwards, part.) 



Carapace of moderate width, anteriorly subquadrate. crossed 

 by broken transversa lines; frontal lobes sinuous; five distinct 

 lateral teeth; X. T. S prominent; E usually prominent. 



Tvpe. E. herbstii (Milne Edwards). Includes occidentalis 

 (Saussure), americanus (Saussure) {=areolatus Benedict and 

 Rathbun), serratus (Saussure). chilensis (Milne Edwards and 

 Lucas) [=validus Smith), rugosus 1 A. Milne Ed wards ),crassus 

 1 A. Milne Edwards), purpureas (Lockington,) bermudensis 

 I Benedict and Rathbun) [=wurdemannii Benedict and Rath- 

 bun, not Gibbes ). convexus 1 A. Milne Edwards ). africanus (A. 

 Milne Edwards 1. bradleyi (Smith) and harttii (Smith). 



The species texanus (Stimpson) ^including texanus sayi 1 

 (Smith)) and packardii (Kingsley as Panopeus, SVeopanope 

 pourtalesii A. Milne Edwards^, are united under Xeopauope 

 A. Milne Edwards. 



A new genus. Hexapanopeus, is proposed for the narrow. 

 hexagonal species of Panopcus with rapidly converging pos- 

 tero-lateral margins. Here belong august if rons (B. & R., 

 type), hemphillii (B. & R.) and caribous (Stimpson a.sJJ/cro- 

 panope) . 



The species Pauopcus harrisii ( Gould) {=wurdemannii 

 Gibbes not B. & R.) is made the type of a distinct genus 

 Rhithropaxopeus [''PeiOfjov, a river or stream). It is narrow, 

 approaching the Carcinoplacinae in form, the dorsal ridges 

 are prominent, and the third abdominal segment does not 

 touch the coxae of the fifth pair of feet. 



So. Eupanopeus herbstii {Milne Edzvards). 

 Bahama Banks. 



1 A series of forms intermediate between texanus and sayi were collected 

 by the United States Fish Commission at Indian River, Florida, in 1896; 

 the latter form is therefore a geographical variation of the former.
