THE NAUTILUS. 25 



Littorina scutulata Gld. Littorina stitchana Phil. The former 

 not very common, the latter abundant and varying greatly in 

 color. 



Lacuna divaricata Fabr. Fairly common on rocks. 



Calyptraea mamillaris Brod. Common in 15-25 fathoms. 



Orepidula nivea Gld. Orepidula dorsata Brod. Neither very 

 common, but found occasionally from low tide line to 30 

 fathoms. The young of the former species is frequently found 

 on the operculum of Priene. 



Natica clausa B. & S. Rather common 15-40 fathoms. 



Lunatia pallida B. & S. Not rare in 50-60 fathoms. 



Velutina laevigata Linn. Fairly common in spongy growth 

 on rocks near low tide line. 



Velutina cryptospira Midd. Found common only in one local- 

 ity. A short distance off shore was a large rock with a crevice 

 ten to fifteen ft. wide worn right through the center from one side 

 to the other. The water in this crevice was deep and the walls 

 nearly perpendicular. On these walls at about the extreme low 

 tide mark were great numbers of Ascidians and in these crypto- 

 spira was found in abundance. Though it was seldom smooth 

 enough to allow me to enter this crevice with a boat at extreme 

 low tide, I was able to do so on two or three occasions and 

 obtained a fine series of living specimens. Some of these were 

 very large, one measuring 31 by 28 millimeters. I am very 

 much averse to referring this and the next species to the genus 

 Velutina, as in life they are so entirely dissimilar to laevigata, 

 the type of that genus. In laevigata the shell is mossy and is, 

 so far as I have seen, entirely bare, while in these two species 

 the shell is smooth and completely covered by the animal. On 

 the other hand, both the animal and shell differ markedly from 

 the genus Lamellaria. 



Velutina rubra, new species. Description. In life similar to 

 V. cryptospira but animal bright vermilion in color (this color 

 soon disappears in alcohol). Shell smaller than that of crypto- 

 spira, rounder and with only a trace of spire. The type meas- 

 ures 13 mm. in length by 9 mm. in breadth. This type to- 

 gether with four additional specimens were taken on Forrester 

 Island by the writer. Three of these specimens were found at
