 stitial threads on the last whorl or two), with a much broader, more

 ture, where a narrower spiral shows below it ; the last whorl quite 

 convex just below the prominent rib. the base moderately convex, 

 and sculptured with 14 beaded spirals, contiguous toward the periph-

GENERAL NOTES. 



Only a Oxe-tenth Oyster Crop This lias been the poorest 



year in ten in the oyster industry of Maryland. In years past from 

 5,000,000 to 10,000,000 bushels of oysters have been taken from the 

 bay. This \ear the yield will be about 1,000,000 bushels. 



The question of legislation for the protection of the oysters has 

 agitated the state for years, but in the meantime the bivalve is dis- 

 appearing. Notwithstanding the diminishing supply, however, there 

 have been sufficient oysters to keep going all the packing houses in 

 Baltimore, which employ about 5000 people. Nearly 500 dredging 

 boats are sailing out of Baltimore. — Phila. Record, Dec. SO. 



Bivalve Shells Used in .Manila fob Window Panes. — 



In .Manila, where there is an interesting Held open to the naturalist, 

 the natives have an odd substitute for glass. It is ;l bivalve shell of 

 about nine inches of surface, so transparent that print can be readily 

 seen through it, and admitting a mellow light in a room where it 

 is used as window glass. The shell is an attractive object, Hat, 

 and in appearance resembles isinglass. One could almost imagine 

 that it was some skillful invention of the natives, could not the growth 



rinjjrs be readily observed. Tl uter side of the shell is perceptibly 



rough, while the interior is perfectly glazed over and in the light has 

 the pearly lustre found in many of the thin-shelled, nyster-like mollusks
