326 ACHATINELLA APEXFULVA. 



the apex is brown or ivory-white, coloring various; typically- 

 streaked, banded with white (gulickii pattern), or nearly 

 white, lip livid pink. PL 60, figs. 6, 6a. 



Further west, near the Kaukinehua-Poamoho ridge, Mr. 

 Spalding collected apicata both dextral and sinistral, varying 

 from nearly black through intermediate shades to slate blue 

 or Dutch blue streaked with white, sutural band hazel, orange 

 or chestnut (pi. 60, figs. 7, la, Station 8, in the western ravines 

 of Kaukinehua) ; also the gulickii pattern, suture pale brown. 

 It occurred also over the ridge on the Poamoho side, east of 

 Nicol's camp, Station 9 of the map, pi. 60, fig. 7& from Spald- 

 ing 's no. 317. The gulickii pattern with a pale brown suture 

 also occurs here. 



It will be noted that these streaked forms are not from the 

 ridges but from the lower slopes. It is likely that the Gulick 

 and Newcomb apicata of "Wahiawa" were from still lower 

 forests than those now existing. 



In Ahonui and Kalaikoa Gulick found typical apicata, like 

 those from Wahiawa, and two forms ranked by him as species 

 (gulickii Sm. and lilacea GuL), but which I look upon as 

 merely the locally dominant color-forms of apicata with which 

 they intergrade in a small number of specimens. This blend- 

 ing of lilacea into gulickii and of both into typical Wahiawa 

 apicata is fully established by the abundant suites before me 

 collected by Gulick himself. Moreover, occasional specimens 

 of exactly the same patterns may be found among apicata in 

 the colonies of "Wahiawa" and Kaukinehua. 



The color-pattern called A. gulickii Smith is figured on pi. 

 60, fig. 12, type ; figs. 10, 10a, 13, topotypes, all from Kalaikoa ; 

 fig. 11, from Ahonui, all collected by Mr. Gulick. The streaks 

 vary from dark slate purple to vinaceous drab, and are inter- 

 rupted on the last whorl by a white zone below the periphery 

 and numerous whitish lines on the base. Typically it has a 

 tawny sutural border, and an ochraceous embryonic shell, 

 fading towards the apex. The lighter colored examples have 

 the sutural band buff or indistinct, and the embryonic whorls 

 pale ; the spirals on the last whorl may be reduced to one white 

 line below the periphery, as in fig. 13. The special feature of
