14. Lamljrus (Parthenopoides) calappoides, Adams df White ? 



Two small males are in the ODllection from the Seychelles, 4-12 

 fms. (No. 194). 



They have the carapace relatively somewhat hroader and flatter 

 than in the typical L. calappoides from the Philippines and Eastern 

 Seas, and are possibly distinct. The specimens of L. calappoides in 

 the Museum collection are somewhat more strongly tuberoulated, but 

 vary between themselves as regards this character. 



15. Euxanthus exscnlptns, var. rugosus. 



This designation is proposed for a female specimen obtained on 

 the beach at Darros Island (No. 200), which differs from all the 

 specimens of Euxanthus essscuTptus (E. mammillatus) in the Museum 

 collection in having the elevations or bosses of the carapace very 

 much more rugose and punctulated, so that it has something of the 

 appearance of a specimen of Hypocaelus sculptus. A larger female 

 is in the Museum, collection from Tamatave, Madagascar (JRev. 

 Deans Cowan), from which the figure is taken. As in the speci- 

 mens of the typical form of E. exseulptus in the Museum collection, 

 from Australia and the Philippines, the bosses of the carapace, 

 although distinctly punctulated, are never rugose, I think this form 

 may prove to be sp^pcifically distinct. In E. huonii (referred to in the 

 earlier part of this Eeport and in E. sculptilis) there is an additional 

 autero-lateral marginal tooth developed between the penultimate 

 and last tooth. Eiixanthus exsculptus (Herbst) is referred to by 

 Hoffmann (t. c. p. 38) as occurring at the Mauritius. 



16. Lophactsea semigranosa {Heller). 

 Etoile Island, 13 fms. (a small male). 



This species, which is apparently well distinguished by the dis- 

 position of the granulations of the carapace, which are absent from 

 the mesogastric and cardiac regions, has been hitherto a desideratum 

 in the Museum collection. The outer surface of the chelipedes and 

 the margins of the ambulatory legs are clothed with hairs, and a few 

 similar hairs exist on the sides of the carapace near the antero- 

 lateral margins. The coloration (in spirit) is pinkish or yellowish. 



17. Lophozozymus dodone (Herbst) ? 



An adult male, obtained on the beach at Mozambique (No. 224), 

 is referred to this species. 



In this specimen the front is rather narrow and prominent, with 

 scarcely any trace of a median emargination ; the teeth of the 

 antero-lateral margins have some indications of having borne setce, 

 as described by Hilgendorf. The merus of the chelipedes is cari- 

 nated above, the wrist has a cristated lobe on its inner surface ; the
