DUTCH BORNEO-EXPEDITION. 147 



head and tail and the margin of the foot are marked with 

 black spots; the ground-colour remains unspotted at the 

 sides of the body below the pouch , on the keel and lower- 

 most part of the pouch itself. The three zones of the foot 

 are unspotted , and of the same colour as the upperside ; the 

 large mucous pore of the posterior end is provided above 

 with a hornlike process. The keel of the intestinal pouch 

 is not very prominent, and through the hole in its centre a 

 golden yellow shell is visible; this latter is lustrous, pro- 

 vided with rather distant concentric folds , and seems to 

 be thin, transparent, slightly calcareous in the centre, 

 with a membranaceous margin. 



Length of the animal (in spirits) about 31 , that of the 

 mantle 18 mill.; breadth of the foot S^/g mill. 



Length of the shell about 12%, breadth 8 mill. 



Localities: Smitau , December 1893 and June 1894 

 (Biittikofer). — Sintang (Goedhuis). 



I can find no species with which our specimens may be 

 identified ; they differ from both species described by Issel. 

 P. Doriae Issel is distiuguished by having conspicuous 

 dark spots ; the new species agrees in colour more with 

 P. Bexcarii Issel , but the latter is still much more spot- 

 ted ; moreover P. Goedhuisi has a much more oblong shell. 

 Issel says that the shell in P. Beccarii is »luteo-viridescens", 

 in P. Doriae »rufa". The space occupied by the intestinal 

 pouch is considerably larger in P. Goedhuisi than in any 

 of the other known Bornean species. 



4. Parmarion Doriae Issel. 



Issel, Molluschi Borneensi, in: Ann. del Mus. Civ. di 

 Stor. Nat. di Genova, vol. VI, 1874, p. 388 ; pi. 4, figs. 7, 8. 



Localities: Top of Mount Daraoes, near Sambas, 1100 — 

 1300 feet (Hallier). — Mount Kenepai (Büttikofer). 



With some doubt I have identified these two specimens 

 with P. Doriae of which only one specimen was known; 

 the dark spots on the mantle are distinct, on the tail 

 they are very obsolete if present at all in the specimen from
