have not been able to determine the exact proportions yet), and 

 thoroughly dissolved ; it becomes now somewhat more limpid, 

 and is used as one would use balsam. It requires a very high 

 heat to boil, so the slide must be heated cautiously ; but there 

 is no difficulty in boiling, and this should be continued for a lit- 

 tle while, when the cover will settle down entirely free from 

 bubbles, and, if the user is careful not to slide it, may be gently 

 pressed down. When cold, the deep color will disappear and 

 the cover will be very firmly fixed. To use this medium, the 

 best polished slides must be obtained, as all the pits and scratches 

 of ordinary slides show up very disagreeably. The covers also 

 must be well cleaned. I have preparations which were made 

 with this material more than three months ago, that show no 

 symptoms of change. 



Too much sulphur, however, will, in time, crystallize. I can- 

 not now state what proportions can be safely used, but the 

 amount named above, thus far appears within limits. 



NOTICE OF A NEW LOCALITY FOR HAPLOPHRAG- 

 MIUM CASSIS, A RARE FORAMINIFER. 



BY A. WOODWARD. 

 {Read April ibth, 1886.) 



While spending my vacation during the summer of 1884 on 

 Peak's Island, situated in Portland Harbor, Maine, I dredged for 

 microscopical objects in the channel between Peak's and Great 

 Hog Islands. 



The depth of water was from about four to thirteen fathoms 

 at low tide. 



I made several very successful hauls, bringing up many 

 species of Gasterpods, Lamellibranchs, Crustaceans, etc. ; also 

 much mud of a bluish gray color, some of which I washed care- 

 fully through a fine-meshed cloth until the water ran perfectly 

 clear. Upon examining the residue with a pocket lens, I found, 

 to my surprise, the very rare arenaceous foraminifer, Haplophrag- 

 miiim cassis, in great abundance, associated with the following 

 forms, which are common on our coast; viz., 



Biloculina ringens, Lamarck, sp. 



Nonionina depressula. Walker and Jacob, sp. 



Polystomella striatopunctata^ F. and M,
