10 PROCEEDINGS OF THE NATIONAL MUSEUM v.n.. 70 



Type from J. B. Henderson's station 330, off the Sambo Reef, 

 Florida, in 120 fathoms. Other specimens are received from Maine 

 and Florida, in 144 fathoms. 



PUNCTURELLA PALPER, new species 



Shell quite small, yellowish white, with about 40 radiating sub- 

 equal ribs, alternately slightly larger and smaller, reticulated by 15 

 or 20 low lamellae, stronger toward the margin, not nodulous where 

 they cross the ribs; the interstices are square, not punctate; apex 

 acute, not coiled; the slit narrow, nearly reaching the apex; interior 

 smooth, the margin slightly crcnulatc; the anal fissure not provided 

 with tube-like roof, but a small straight lamina bounds it behind; 

 height of shell, 3; length, 5; diameter, 4 ram. U. S. Nat. Mus. Cat. 

 No. 93906. 



Dredged by the United States Bureau of Fisheries at Station 2135, 

 south of Cuba in 250 fathoms, coral sand. 



The shell is small, and niay be immature but is quite distinct from 

 the other known species of the coast. 



In examining a very large number of specimens from the eastern 

 coast of North America I find that in P. prlnceps and its variety (?) 

 the presence or absence of props to the inner septum is an inconstant 

 feature. They are usually, but not always, absent in the young and 

 not always present in the adult. On the other hand, in some species 

 their presence or absence appears to be a constant character. Among 

 our northern forms P. prlnceps is marked by distinct punctuation 

 in the interspaces between the ribs and an obscure beading on the 

 ribs. In the supposed variety the ribs and interspaces are smooth. 

 The latter closely resembles the European noachina and may be con- 

 specific. Adult normal specimens usually have props to the septum. 

 P. noachina is figured and described as possessing props but well 

 grown specimens received from authentic sources in our collection 

 are without them, while others possess them. 



SCISSlJRELLA PROXIMA, new speiies 



Shell minute, white, of nearly four whorls, the slit about one-fourth 

 as long as the whorl; the suture distinct, not deep; the posterior sur- 

 face between the suture and the fas<dole arcuately striated; the base 

 moderately convex, the surfa,ce nearly smooth, but under the lens 

 showing a faint reticulation of the incremental lines with faint spiral 

 threads; umbilicus perforate; the aperture rounded the pillar lip 

 slightly reflected; height, 1.7; diameter, 3 mm. U. S. Nat. Mus. 

 Cat. No. 322962. 



Dredged oft' South Carolina by the U. S. Bui'cau of Fisheries 

 steamer Albatross at station 2314, in 159 fathoms coarse sand, bottom 

 temperature 47.4° F. 



The species is smaller and relatively more elevated than S. crispata; 

 less elevated and with much less prominent sculpture than S. alia
