XXXV. — On a Collection of Crustacea from the Malaysian 

 Region. — Part III. Crustacea Anomura and Macrura (ex- 

 cept Penseidea). By Edward J. Miers, F.L.S., F.Z.S. 



[Continued from p. 317.] 



Anomura. 



Dromiibea. 



Dromia vulgaris, M.-Edw. 



A fine adult male is in the collection (without definite loca- 

 lity) which does not seem to differ specifically from the Medi- 

 terranean D. vulgaris. The tubercle or accessory tooth at 

 the base of the second antero-lateral marginal tooth, how- 

 ever, is more developed than is usually the case in D. vulgaris. 

 A specimen undoubtedly belonging to D. vulgaris is in the 

 Museum collection from Gen. Hardwicke, and therefore pre- 

 sumably from the Indian Ocean. 



Dromia Rumphii, Fabr., junior? 



I refer, with some hesitation, to this species a female 

 Dromia which differs from adult examples of D. Rumphii in 

 the proportionally narrower, more elongated carapace, the 

 front and sides of which slope much more steeply (almost 

 vertically) to the rostrum and antero-lateral margins. The 

 carapace is much more convex anteriorly and is covered with 

 a much shorter, more scanty pubescence. The median tooth 

 of the rostrum is nearly obsolete ; and the fifth pair of legs is 

 relatively more elongated. The exact locality of this speci- 

 men has not been preserved. Length 1 inch 7 lines, breadth 

 nearly 1 inch 9 lines. 



I have observed very similar differences between adult 

 D. vulgaris and a series of young Dromice from Sardinia in 

 the Museum collection. 



Dromia (Dromidia) orientalts, sp. n. 

 (PL XV. figs. 1, 2.) 



Carapace convex, but little broader than long, and covered 

 with a close velvety pubescence, which (probably through 

 abrasion) is thin or absent on the gastric and cardiac regions ; 

 the sides slope very steeply, almost perpendicularly, to the 

 antero-lateral margins. No sutures are visible on the upper 

 surface. Front quinquedentate (the supraocular tooth in- 

 cluded), the median tooth smallest, the others rather promi-
