314 FAUNA HAWAIIENSIS 



(51) Achatinella [Partulina) lignaria Gulick. 



Achatinella lignaria Gulick, Ann. Lye. New York, vi. p. 209, pi. vii. fig. 35 (Dec. 



1856). 

 Hab. Maui, Wailuku (Gulick). 



var. crocea Gulick. 



Achatinella crocea Gulick, t. c. p. 21 i, pi. vii. fig. 36 (Dec. 1856). 

 I think A. crocea is only a variety ; both were placed by Newcomb as synonyms 

 of his A. terebra. 



Hab. Maui, Waihee (Gulick). 



(52) Achatinella [Partulina) marmorata Gould. 



Achatinella marmo7'ata Gould, P. Boston Soc. 11. p. 200 (1847); U. S. E.xplor. 

 Exped. Moll. fig. 94; Newcomb, Ann. Lye. New York, vi. p. 311 [animal]; 

 Gwatkin, P. Ac. Philad. 1S95, P- 238 [radula]. 

 Achatinella adamsi Newcomb, Ann. Lye. New York, vi. p. 19 (May, 1853); 



P. Zool. Soc. London, 1853 [1854], p. 137, pi. xxii. fig. 20 (as A. adamsii). 

 Achatinella indicia Gulick, Ann. Lye. New York, vi. p. 207, pi. vii. fig. 34 (Dec. 



1856). 

 The synonymy of this species is difficult ; Newcomb united two other forms de- 

 scribed by Gulick from a different district of Maui ; Mr Baldwin on the other hand 

 regards them as species. For the present I have left them, with some hesitation, specific 

 rank ; they are A. ustulata and A. plumbea. 



Hab. Maui, Haleakala (Gould); Makawao (Newcomb, Baldwin); Wailuku 

 (Gulick). 



(53) Achatinella [Par/ulina) niighelsiana Pfeiffer. 



Achatinella mighelsiana Pfeiffer, Mon. Hel. Viv. 11. p. 238 ; Newcomb, Ann. Lye. 



New York, vi. p. 319 [animal]; Gwatkin, P. Ac. Philad. 1895, P- 238 [radula]; 



Reeve, Conch. Icon. Achatinella, sp. 40. 



The typical form is a whitish shell with a single black band at the periphery ; this 



sino-le band is occasionally split into two smaller ones. Some lovely varieties were 



collected by Mr Perkins, which may be tabulated as follows : 



(a) White and bandless. 



(y8) Bandless, of a rich orange hue with strigations of a slightly darker shade, 

 tubercle white.
