roiiuded ; second and third large ; last tooth small and pointed. Cheli- 

 peds finely grannlated and rugose. 



Length, 9 millimetres ; width, 13 millimetres. 



West Indies, 73 to 118 fathoms. 



10. Panopeus herbstii granulosus A. Milue Edwards. 

 Miss. Sci. au Mexique, pt. 5, i, p. 309, 1880. 



Variety of herbstii found at Bahia, Brazil, and remarkable for its wide 

 and very granulate carapace. 



11. Panopeus crassus A. Milne Edwards. 



Loc. cit., p. 313, pi. LVii, tig. 1. 



Distinguished from herbstii by its wider carapace, less convex trans- 

 versely, and much swollen mesogastric region. Autero-lateral portion 

 finely granulated. Front much produced, horizontal. External angles 

 sharp, and produced much in advance of the orbital angles. Chelipeds 

 very strong. 



Length, 36 millimetres ; width. Go millimetres. 



Brazil. 



12. Panopeus lugosus A. Milne Edwards. 



Loc. cit.. p. 314, pi. LVII, fig. 4, 



Carapace very wide and granulate. Epigastric, protogastric, and 

 protobranchial regions with prominent transverse lines. Front with 

 triangular median notch, not a straight fissure, as in herbstii and crassus. 

 Front four-lobed, median lobes rounded and produced, lateral lobes 

 nearly straight. External angle of orbit little advanced and separated 

 from the first autero-lateral tooth by a slight sinus. All the teeth are 

 })ordered by a line of granules. Chelipeds covered with fine granules. 

 Hands with two prominent longitudinal lines above. Ambulatory feet 

 long, dactyls slender. 



Species easily distinguished by the form of the front, by the antero- 

 lateral teeth, by the granulation of the carapace and chelipeds, and by 

 the length of the ambulatory feet. 



Length, 39 millimetres ; width, GO millimetres. 



Bahia, Brazil. 



13. Panopeus convexus A. Milne Edwards. 

 Loc. cit., p. 316, pi. LViii, fig. 5. 



Edwards says of this species : 



Carapace very convex in both directions. Areolations prominent ; 

 nearly smooth. Front less advanced than in chilensis, more depressed, 

 lateral angle less conspicuous. External orbital angle not produced, 

 scarcely separated from the first antero-lateral tooth. (Fig. 5, loc. cit., 

 represents it as deeply separated.) 



Length, 25 millimetres; width, 3G millimetres.
