HAWAIIAN NESOPUPAE. 301 



1.95, diam. 1.15, apert. (diag.) 0.8 mm. The color of fresh 

 typical specimens from Hilo, Hawaii is buckthorn-brown. 



130. Form gouveia C. & P. PL 29, fig. 4. 



A very small race of wesleyana was found by Gouveia at 

 Hookena, and by Forbes at Kapua, both localities in South 

 Kona, Hawaii. In this form the outline is narrowly ovate, 

 tapering above. The aperture is truncately ovate, its outer 

 margin hardly flattened. Whorls 4%. In cross section the 

 upper palatal is only slightly bent ; the angular unites with the 

 outer lip at a slight distance from the margin. Length 1.65, 

 diam. 0.98, apert, (diag.) 0.73 mm. Type 11081 Bishop 

 Museum, paratype 39429 Bishop Museum, and 44732 A. N. S. P. 



13&. Form tryphera C. & P. PL 29, fig. 3. 



A form which is usually smaller than the typical and which 

 appears to occur in pure colonies, has the upper palatal fold, 

 abruptly bent in the middle, the inner half descending towards 

 the lower palatal fold. A few of the specimens from Oahu 

 (Nuuanu, Makiki and Moanalua, coll. by Spalding), are nearly 

 equal to the typical form in size, but the majority of the 

 colonies are decidedly smaller. Embryonic whorls similar to 

 those of the typical form. 



Typical examples of this form have been taken from the 

 following localities: Kauai : Lihue. Oahu: Palolo (type loc.), 

 Tantalus, Nuuanu and Kaipapau, in the Koolau Range; 

 Palehua and Popouwela, in the Waianse Range. Molokai : 

 Puunea and Mapulehu (Thaanum). Except for the larger 

 form from Oahu mentioned above the examples are remark- 

 ably uniform in size and other characters. Length 1.75, diam. 

 1.1, apert. (diag.) 0.8 mm. 4% whorls (Palolo). Type 11082
