ZOOLOGISCHE MEDEDEELTKGEN — DEEL IV. 



Hussin, July 1910. 



This species is allied to P. macgregori Hedley (Proc. Lin. Soc. N. S. 

 Wales, 1891, p. 82, PL 10, fig. 17, 19), which, according to Pilsbry, should 

 be the same as dominida Tapp. Can., but is still much flatter, the peristome 

 more flatly expanded, the crest in the new species is only visible on the 

 base, the umbilicus is more open, the dark colour of the peristome is 

 expanded on the outer part of shell and in the aperture.

Hussin, July 1910. 



This specimen agrees in nearly every respect with P. tortilabia, but 

 the shell is covered with small pits, having the appearance of hair-scars; 

 neither in littérature nor on the numerous specimens of that species I 

 have seen, I can find anything of this kind mentioned or visible ; this 

 makes me doubtful as to the identification, but as the specimen is rather 

 worn, I cannot resolve to describe it as new, though, if fresh specimens 

 in larger number could be compared, the necessity of describing and naming 

 might be obvious. 



4. Planispira (Cristigïbba) musgravei Smith, var. efasciata n. var. 



Smith. Ann. Mag. Nat. Hist. Ser. 6, Vol. XV, p. 233. lb. Vol. XVI, p. 363, 

 PI. 20, fig. 13—15. 



Upper part of Sermorvai-river, April 1, 1911. 



Mr. Gude has had the kindness to compare this species ; in the specimen 

 at hand, the hairs are still present, but the blackish band is wanting 

 and the peristome is purplish-brown (white in the type); so the species 

 seems to be variable in these respects, like so many ones in this genus, 

 a. o. P. tortilabia. 



Chloritis Beck. 



1. Chloritis dinodeomorpha Tapparone Canefri. 

 Tapp. Canefri. Fauna Mal; N. Guinea, p. 168, PI. 4, fig. 4—7. 



No special locality mentioned. 



The only specimen is a little smaller, its diam. maj. being only 28' / 2 

 mill. (31 in the type), its peristome is a little more curved above, the 

 umbilicus slightly more open, but these differences are most probably 

 only individual.
