SPECIES OF PlLUMNUS REMOVED TO OTHER GENERA. 



P. glaberritnus, Haswell, 1881. Now Oeratoplax glaber- 

 rimus (Haswell) = C. punctata, Baker, 1907. Haswell's 

 type examined. 



P. inermis, Haswell, 1881. Now Ceratoplax inermis 

 (Haswell). Type not found; specimen from Saddleback 

 Island, Queensland, examined. 



P. integer, Haswell, 1881. Photographs of type (dorsal 

 views) examined. Should be referred to Chasmocarcinus 

 or a kindred genus. 



P. pilosus, Fulton and Grant, 1906. Now Heteropilum- 

 nus fimbriatiis (Milne Edwards, 1834). Not P. fimbriatus, 

 Haswell, 1882 = Cryptoc&loma fimbriatum, Miers, 1884. 

 See de Man (who examined Milne Edwards 's types), Zool. 

 Jahrb., Syst., viii., 1895, p. 533. 



P. fimbriatus, Haswell, 1882. Now Cryptocceloma 

 haswelli, nom. nov. == C. fimbriatum, Miers, 1884, not P. 

 fimbiatus, Milne Edwards, 1834. Male specimen from 

 Port Denison, Queensland, examined. 



PILUMNUS SPONGIOSUS, Nobili. 



Pilumnu-s spongiosus, Nobili, Bull. Mus. Hist. Nat., Paris, 



1905, No. 6, p. 406; Ann. Sci. Nat., Zool. (9), iv., 



1906, p. 280, pi. x., fig. 6. 



South of Gabo Island, Victoria, 200 fathoms; E.6212; 

 one male. Carapace length 5.6 mm., width 7.1 mm. 



This specimen is much smaller than those described by 

 Nobili; the carapace is proportionally narrower than that 

 of the female measured by him, the distance being shorter 

 from the orbit to the second of the five lateral teeth. In 

 nearly every respect the "Endeavour" specimen agrees 

 with the descriptions cited; there is, however, indication 

 of a transverse fringe of hair on the front, though it is 

 incomplete ; the pubescence in front of the fringe is shorter 

 than behind it ; only one row of granules is discernible on 

 the margin. It may be added that both fingers of both 

 chelae are deeply grooved, and the granulation extends 

 half the length of the dactyls and almost to the tips of the 

 immovable fingers.
