ISOPOD GENUS LIGIA. 701 



I have not seen specimens of the following species : — 



16. LiGiA DiLATATA Brandt. 



Ligia clilatata Brandt (1833), p. 171. 

 Lygia clilatata Krauss, Siidafrik. Crust., 1843, p. 62. 

 Ligia clilatata White, List Crust. Brit. Mus. 1847, p. 98. 

 ■ Ligia clilatata Budde-Lund (1885), p. 262. 



Ligicc clilatata Stebbing, Ann. South African Mus. 1910, vi. 



p. 437. 

 Ligia clilatata Collinge (1920), p. 475. 



Distrihit,tion. Cape Peninsula. 



Collinge has re-described and figured this species in the last- 

 named work, but has added little to Budde-Lund's previous 

 description. Reasons for legarding Z. glccbrata and L. gracilipes 

 as independent species and not as shown in Collinge's synonymy 

 are given above. 



17. Ligia richardson^ (Pearse). 



Ligyda richarclsonce. Pearse (1915), p. 549. 



Distribution. Sierra Nevada de Santa Marta, Colombia, at 

 3800 ft. elevation. 



Fully described and figured by Pearse. 



18. Ligia simoni (Dollfus). 

 Geoligia simoni Dollfus (1893), p. 343. 



Distrihibtion. Valencia, " vers 1200 metres d'altitude, dans les 

 forets." 



This species only appears to difier from the preceding in the 

 greater relative breadth of the body and the larger size of the eyes. 

 Dollfus's description is based on a single male specimen, however, 

 and occurring as they do so close together, it is probable that 

 collection of further material will show them to be identical. 



Figured and briefly described by Dollfus. 



The following species are insufiiciently described or of doubtful 

 validity : — 



19. Ligia cajennensis Koch (1847). 



20. Ligia australiensis Dana (1852). 



21. Ligia cursor Dana (1852). 



22. Ligia vitiensis Dana (1852). 



23. Ligia malleata Pfeflfer (1889). 



Distribution Bagamoyo. 



The description of this species and the locality in vphich it was 

 found suggests its identity with lAgia exotica. Pfefi"er does not, 

 however, mention the character of the 1st leg nor the sex of the
