GASTROCOPTA, EAST INDIES, POLYNESIA. 149 



G. p. ovatula (Moellendorff). PL 25, figs. 13, 15. 



It differs from the type by the regularly ovate shell, less 

 lengthened, and a little smaller. Alt. 2y s , diam. max. l 1 ^ mm. 



Philippines : Cebu, at the town of Guadalupe. Also Siqui- 

 jor, Mindanao, Leyte, Bohol, Luzon, etc., and Yap, Caroline 

 Is. (Mlldff.). 



Leucochilus pcdiciilus var. ovatula Boettger, MOELLEN- 

 DORFF, Bericht Senckenb. uaturforsch. Ges. Frankfurt, 1890, 

 ,p. 253; 1893, p. 100. Verzeichniss, etc., p. 127, in Abhandl. 

 uaturforsch. Ges. zu Gorlitz, xxii, 1898, p. 153; Journ. of 

 Malacol., vii, p. 113. 



"Different from the Polynesian type only by the shorter, 

 more compact form : the examples are 5-toothed, the parietal 

 tooth distinctly bifid, the basal tooth very weak. The same 

 variety, wholly agreeing in size, shape and dentition, occurs 

 also on the islands Siquijor and Mindanao, as well as upon 

 Yap, Carolines. 



" 'Pupa capillacea' of Hidalgo, J. de Conch., 1888, p. 38, 

 from Naga, Cebu, is certainly not the species described by 

 Dohrn and Semper from Mindanao, but most likely the above- 

 described variety of L. pediculus" (Mlldff.). 



The Bohol specimens figured (pi. 25, figs. 13, Loboc, and 

 15, Sierra Bullones. Bohol) were received from Quadras under 

 the above name. The shape seems rather variable, both lots 

 having shorter and larger examples, but all agree in the very 

 small size, or absence, of the basal fold. This is also charac- 

 teristic of the Hawaiian race, and of that inhabiting the coast 

 of Queensland. 



G. p. nacca (Gould). PL 25, figs. 6, 7. 



The teeth are a little smaller than in typical p<~diculus, the 

 parietal lamella shorter, and the basal either wanting or very 

 small. The upper palatal plica is short, and there is often a 

 small interpalatal plica below and near it. Infraparietal 

 nodule very small or wanting. It is often somewhat narrower 

 than the examples figured. Length 2.6, diam. 1.3 mm. (fig. 6). 



Hawaiian Is.: Hawaii (Dr. Newcornb), Waipio Valley 

 (Thaanum). Oahu: Maiioa Valley (figs. 6, 7) and west of 

 Kahuku (Pilsbry and Cooke).
