356 NEWCOMBIA AND PARTULINA. 



It will be seen that east of Kaluaaha there are only smooth- 

 ish variants of cinnamomea; west of Kahaanui a long series of 

 parallel valleys and ridges supervenes in which no allied form 

 has been found, cinnamomea appearing again in Makolelau 

 in a ravine east of the house, and in a small ravine east of 

 Puu Kolekole (Cooke & Pilsbry), and further west in Maka- 

 kupaia. 



"Where the connection between the eastern and western 

 herds finds place, if at all, is not clear, as we saw nothing of 

 the species in the region above the Kamalo amphitheatre, 

 where Thaanuni and others also have collected.

It is interesting to find that this most primitive of existing 

 Newcombias occurs in the Pleistocene shell-beds of Moomomi 

 (Cooke & Pilsbry, 1913). Like the other tree-shells of the 

 dune deposits, it is rather rare.

P. ORNATA (Newc.). Page 18. By an oversight the locality 

 was given as East Maui. Very beautiful specimens have been 

 taken by Mr. Thaanum on Mt. Helu and Mt. Lihau, both in 

 West Maui. The only other locality known is that given by 

 Newcomb.

Page 16. The quotation from Newcomb on p. 17 might give 

 a false idea of the abundance of this species. It is a common 

 shell on shrubs of many kinds, from the head of Karnalo to 

 the region of Puunea, at the present western limit of tree- 

 snails; found only on the high part of the island, of course. 

 No doubt Newcomb 's type was from the Puunea region, some- 

 where between Meyer's place and the north cliff. 



Different colonies, even in the same neighborhood, are often 

 unlike in markings. Thus, on the margin of the flat north of 

 Meyer's lake the patterns of pi. 4, figs. 1-5 prevail, but there 

 are also a few of the balteata pattern, similar to pi. 4, fig. 7.
