PiANAXIS LONGISPIKA, Smith. 



Planaxis lo7igispira, Smith : Ann. Mag. Nat. Hist., 1872, vol. ix, 

 p. 45 ; Sowerby in Reeve's Conch. Icon., vol. xx, pi. iv, fig. 32. 



Hab. — Chinese seas (Hanley Coll.). 



Three specimens from Christmas Island in fresh condition show 

 that the spire is not always smooth as originally described. Apparently 

 the types from the Hanley collection, which are now in the Museum, 

 were rather worn, and did not show the spiral striation, which is 

 present, at all events, upon the upper whorls. One of the three shells 

 obtained by Mr. Andrews is of the same elongated form as the type, 

 but the others are somewhat shorter. Of the latter, one has three fine 

 red lines upon that body- whorl, whereas the other and the elongated 

 specimen also have but a single line just above the periphery', which 

 passes up the spire. 



LiBITINA OBLONGA (LiuU.). 



Chama ohlonga, Linn. : Gmelin, Syst. jS'at., vol. vi, p. 3302. 

 Cypricardia Guinaica, Chemn. : Reeve, Conch. Icon., vol.i, pl.ii, fig. 13. 

 The single specimen from Christmas Island agrees with Cypricardia 

 Guinaica as determined by Reeve. This sliell also seems to be the 

 Chama ohlonga of Linnaeus as defined by Gmelin, Chemnitz, Lamarck, 

 and Hanley. The specimens figured by Reeve as Cy. ohlonga (Conch. 

 Icon., figs. 4<?., 4.a) belong to a different form. 



Teredo and Xylotrta spp. 



Two or three species of Xylotrya, judging from the pallets, were 

 obtained from piles in Mying Fish Cove. IJnfortunately the pallets 

 were separated from the soft parts, and only one shell was obtained 

 attached to an animal, and this was without pallets. Under these 

 circumstances it does not seem advisable to name these species. 

 A species of Teredo (animal and pallets only) was found in the same 

 balks of timber. The pallets of one specimen of Xylotrya are about 

 4 inches in length. 



Ennea (Huitonella) bicolor (Hutton). 



This species occurs in many localities, and doubtless this has led 

 to its being described five times nnder different names. It is Ftipa 

 Largillierti, Philippi ; Pupa mellita, Gould ; Pupa Ceylanica, Pfeiffer ; 

 and Pupa cafceicola, Craven. 



It has been recorded from many localities in India, also from 

 Burmah, Rangoon, Arakan, Cochin- China, Singapore, Pulo Pinang, 

 Andaman and Nicobar Islands, Ceylon, Reunion, Seychelles, 

 Mauritius, Nossi Ee, Timor, Amboina, Madura, and Sarawak. It also 

 occurs in the West Indies, at Trinidad, St. Croix, St. Thomas, 

 St. Lucia, and Granada, where it has probably been introduced by 

 human agency.
