GUDE : HELICOID LAND-SHELLS FROM JAPAN & THE LOO-CHOO IS. 1 95 



only known species to be compared with this form is P. trochula, 

 but that shell is much smaller and more depressed, the umbilicus is 

 narrower, the cuticular lamellae are much more interrupted, the spiral 

 sculpture is much finer, and the aperture less circular. 



39. Eulota (Plectotropis) Kiusiuensis, Pils. PI. XXI, Figs. 10-12. 

 Kikai-ga-skiina, Loo-Choo. 1 Three specimens. The one figured was 

 received from Messrs. Sowerby and Pulton. Mr. Pilsbry in his 

 description compares this shell to P. trochula ; it seems to me, however, 

 that it has more affinity with the next form. 



40. Eulota (Plectotropis) delectabilis, Ehrm. Naha, Loo-Choo. 

 The shell referred by me to P. elegantissima, Pfr. (ante, p. 16, PL II, 

 Pigs. 15-17), has been shown by Dr. Ehrmann to differ from Pfeiffer's 

 species, and he has based a new species upon it. I do not think, 

 however, it can be considered of more than varietal rank. 



41. Eulota (Plectotropis) elegantissima, Pfr. A single specimen 

 from Loo-Choo agrees with Pfeiffer's types in the British Museum. 



42. Eulota (^Egista) mimula, Pils. Kashima, Harinia. One 

 specimen. Kioto. Two specimens. Kayabe, Ojima. Six specimens. 

 The smallest species of this section. Diam. maj. 10, min. 8 5 mm. ; 

 alt. 5"5 mm. 



43. Eulota (^Egista) Fkiedeliana, var. tumida, n.var. Gojo, 

 Yamato. Six specimens. Differs from the type in being darker in 

 colour, in having more tumid whorls, a higher spire, and wider 

 umbilicus, and in the cuticular lamellae being much less pronounced. 

 One specimen has a pale peripheral band, giving the shell much the 

 aspect of E. oculus. Diam. maj. 15, min. 13 mm. ; alt. 8'5 mm. Diam. 

 maj. 15 - 5, min. 135 mm. ; alt. 9 mm. 



44. Eulota (Euhadra) Luhuana. 

 A. Var. Aomoriensis, Pils. & Gul. 



Choja, Mutsu. Three specimens. One specimen has the band 

 formula 00305, lip white : diam. maj. 45 - 5, min. 39 mm. ; 

 alt. 29 mm. A second specimen has in addition diffused second 

 and fourth bands, lip fuscous: diam. maj. 39, min. 325 mm. ; 

 alt. 25 mm. The third is bandless, lip white : diam. maj. 38, 

 min. 33 mm ; alt. 25 mm. 



Gonohe, Mutsu. Two specimens. Pale buff, band formula 00305, 

 one with faint traces of second and fourth bands : diam. maj. 38, 

 min. 31*5 mm. ; alt. 25 mm. 



Ibuki, Omi. Three specimens. Pale straw yellow, two specimens 

 with band formula 02310, bands pale chestnut, interrupted; lip 

 white: diam. maj. 45, min. 38mm.; alt. 30mm. The third 

 specimen with formula 00345, lip fuscous : diam. maj. 41*5, 

 min. 355 mm. ; alt. 27 mm. 



1 Although politically united to the province of Osumi, Japan, this island belongs 

 geographically to the Loo-Choo Islands, being about 15 miles east of Amami- 

 O-Shima, the largest island of the Hokubu-Shoto, or northern group.
