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. 
Crepidula nivea Gld. Crepidula 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. & 8. 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 Jaevigata 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). Shelli smaller than that of erypto- 
spira, rounder and with only a trace of spire. The type meas- 
ures 134 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
