MOLLUSCAN NOTES. 11.^

No. 7. PlANISPIKA. aUADRIFASCIATA, GuilloU, 



Owing to the variation in size of the shell, the denticle on basal 

 portion of peristome, and width of colour-bands, this species has 

 received several names. The synonymy is as follows : — 

 1842. Helix quadrifasciata, Guillou, Rev. Zool., p. 141. 

 1864. H. insirida, Marts., Moiiatsbericht. Berl. Akad., p. 268.

1902. P. roUei, MGlldff., Nachr. deutsch. Malak. Ges., p. 189. 



1903. P. quadrifasciata, var. halmaherica, Glide, Journ. Malac, vol. x, 



p. 48, pi. iii, fig. 2. 



The instricta, Marts, (afterwards changed to quadrifasciata, var. 

 edentula, Marts.), has only a slight swelling at the usual place of the 

 denticle. P. rollei, Molldff., is a small specimen, otherwise typical. 

 P. Icendigiana, Rolle, is simply a variety with wide bands. P. quadri- 

 fasciata, var. halmaherica, Gude, was described from a specimen with 

 three colour-bands only, otherwise it appears to be quite typical. 



No. 8, — Helix nodifera, Pfr. 

 This species is evidently the large form of Papuina grata, Mich., 

 as recently collected by the brothers Meek at Muswar Island, Dutch 

 New Guinea, and described by me as P. grata, var. magna. The 

 absence of the usual colour-band in Pfeiffer's example is probably 

 owing to loss of its periostracum, since specimens before me demon- 

 strate that tlie colour is only in the periostracum, which is of a 

 deciduous character. Although Michaud's figure does not show the 

 cliaracteristic columelhir nodule or swelling, he notes in his description, 

 " au bas de la columelle se trouve une petite dent."

 I stated that I had been unable to find a description of Helicina
