trie lobes which are all but confluent with the protogastric : bran- 

 chial lobes convex, each divided by a transverse valley into an ante- 

 rior and posterior portion ; postero-laterally to the gastric region 

 the surface of the carapace is raised on each side into an irregular 

 areolet bounded antero -laterally by the epibranchial, behind by the 

 meta-branchial lobe from which the cardiac area is separated by an 

 indistinct longitudinal depression ; post-frontal furrow deeply exca- 

 vated behind the eyes ; post-frontal crest scarcely interrupted by the 

 advanced position of the epigastric lobes, continued outwards on each 

 side from the meso-gastric furrow in an irregular, rugose line to the 

 epibranchial teeth ; these pass backwards, as prominent dentate 

 crests and, with the extra-orbital teeth, are extremely salient ; orbital 

 margins finely crenated ; front deflexed, wider at base than at its 

 free margin, raised into two eminences one on each side of the middle 

 line ; antero -lateral portions of the branchial regions marked with 

 numerous coarse granulations ; postero-lateral margins and the parts 

 of the carapace which form the floors of the branchial cavities rugose. 

 Chelipedes slender ; chelse externally rugose, covered, especially on 

 their infero -internal surface, with small rough tubercles. Carpopo- 

 dites above rugose with a longitudinal row of tubercles near their 

 inner margins, from which there projects a very sharp spine with a 

 smaller one below it. Ambulatory legs enormously long arfd slender 

 by which character alone it is possible at once to distinguish T. 

 Austeniana from all its known congeners. 



Breadth, 48 mm. 



Length, , 35 mm. 



Length of carpopodite of 3rd pair of ambulatory legs =34 mms. 

 or nearly equal to the length of the carapace.

Telphusa Pealiana, n. sp., pi. xiv, figs. 7—11. 

 Carapace thick, not much broader than long, convex from behind 

 forwards; its areolation is similar to that of Telphusa Athinsoniana ; the 

 cervical suture cuts through the post-frontal crest about 5 millime- 

 tres internally to the epibranchial teeth ; these are moderately salient ; 

 the branchial region is somewhat convex and covered anteriorly 

 with coarse irregular granulations ; antero-lateral margin inclined,
