LEUCOSOIDEA. 393 



B. CARAPAX TRANSVERSUS, LATERE VALDE DILATATCS, LATERIBUS PEDES 

 RETRACTOS TEGENTIBUS. 



G. OREOPHORUS, Riippell.* Carapax transversim subtriangulatus, latere sub- 



rotundatus, fronte angustus, paulo saliens. 

 G. TLOS, White.-f Carapax transversim subellipticus, regionibus lateralibus con- 



cavis, fronte integro, rotundato, sursum reflexo. 



Mr. A. White also adds to the Leucosidae, the genera Harrovia and Iphiculus (Voy. 

 Samarang, pp. 55 and 57). The latter, as we have observed on a former page, is pro- 

 bably the same with Polydectus. The former has the general habit of the Partheno- 

 pidse (especially Ceratocarcinus, White), not merely in form, but in the long hand with 

 short fingers, and in the position of the hand upon the carpus. Still, if it is like the 

 Oxystomes in the mouth and efferent channel, it belongs with the Leucosidae. On this 

 point we cannot decide, except from the reference of it by Mr. White to this group. 



FAMILY!. CALAPPID^E. 

 CALAPPA TUBEECULATA (Fabr.) 



Sooloo Sea; Feejees and Tongatabu, South Pacific; Sandwich 

 Islands, North Pacific. 



In the Voyage of the Bonite, this species from the Sandwich Islands 

 is figured as new, under the name C. Sandwichensis (pi. 3, f. 9). I 

 find no essential difference between the specimens and that of the 

 tuberculata from the Sooloo Sea.
