1666 Olivella gracilis Gaylordi 



Ford, Nautilus 8:104, named a new variety from the Gulf of 

 Cal. for Mrs. E. M. Gaylord. 



1667 Holopira pasonis 



Dall, Nautilus 8:112, El Paso Co., Texas. 



1668 Unio Oregonensis Lea. 



In the Nautilus 8:116 it is shown that this is a synonym of 

 U. Rowelli Lea, a species of the Central American region. No 

 Unios are known from west of the Rock Mountain chain, so that 

 all references to the Columbia river or Oregon are erroneous. 



1669 Pyramidula Randblphii 



"Shell minute, reddish brown, with dull silky lustre, elevated, 

 with 3% rather inflated whorls; sculpture only of fine incremental 

 lines, barely perceptible under an ordinary triplet lens; suture 

 deep, periphery rounded, slightly less so in the immature shell, 

 but seemingly never angular; aperture obovate, somewhat 

 oblique, wider than high, the body segment about l-3d of the 

 whole; top dome-like, base full, umbilicus small, subcylindric, 

 deep. Alt., 0.75. max. diam. 1.4, min. diam. 1.25 mm." — Dall,

1670 Patulastra? pugetensis 



"Shell minute, pale greenish yellow, nearly smooth, the first 

 whorl and a half smooth, the others with fine, silky, close-set, 

 hardly elevated lines or minute regular riblets, somewhat flex- 

 uous and in harmony with the incremental lines; form moder- 

 ately elevated, the whorls inflated with a deep suture, and, in 

 the adult, rapidly enlarging near the aperture in the latter part 

 of the last whorl; aperture large, quite oblique, almost circular, 

 the segment of the body between the two lips about l-6th of the 

 whole; umbilicus ample, scalar, exhibiting part of all the whorls 

 which make, in adults, from 3 to 3% volutions. Alt. 0.5, max. 

 diam. 1.5, min. diam. 1.2 mm." — Dall, Nautilus 8:130.
