120 THE NAUTILUS. 



ceived the honorary D.D. degree from Edinburgh. In 1882 he 

 published " Studies of Arianisrn." It is very interesting to find 

 that a man who thus gave his life to theological studies, should 

 have chosen for his hobby such a subject as the radulse of the 

 mollusca. His collection, which I was permitted to examine 

 when in Cambridge some years ago, is amazingly rich, doubt- 

 less far exceeding any other. He was indefatigable in securing 

 material from all over the world, and was able to prepare good 

 mounts from animals long dried in the shell. Unfortunately 

 the shells themselves were not usually preserved, so in case of 

 doubtful identifications there will be no ready means of con- 

 firming the assigned names. It is understood that the whole col- 

 lection has gone to the British Museum. T. D. A. COCKERELL. 



NOTES. 



COMMON NAMES : Speaking of common names reminds me of 

 the time I lived in Branford, Connecticut. I used to hear the 

 name "Squaw Clam" frequently. I found the name originated 

 from the fact that in the duck season the old squaws fed on 

 these forms. So I made up my mind to find out what a squaw 

 clam was. I tried Mulinia lateralis with one man : I got " yes, 

 that' s it. " Tellina tenera with another, ' ' yes, that' s it, " Macoma 

 with another, "yes, that's it." I don't know how many species 

 I tried, but I found that squaw clam embraced so many that 

 no genus would hold them. H. W. WINKLEY. 



LIMAX ARBORUM IN A COLORADO GREENHOUSE. In a green- 

 house at Boulder, devoted principally to the growing of tropical 

 orchids, numerous slugs have recently appeared, and have 

 proved extremely destructive to the plants. I have before me 

 a Cattleya flower absolutely ruined by them. There is every 

 reason to believe that the slugs came with a consignment of 

 orchids from Denver, but how they reached Colorado remains 

 unknown. The species is Limax arborum, as I was able to con- 

 firm from an examination of the penis-sheath, which shows the 

 so-called flagellum very well. The specimens are very uniform, 

 all belonging to the variety subrufa LeComte, having the body a 

 rather pale and translucent reddish, mantle with the usual 

 black bands and a nebulous or evanescent median one, back 

 with two grey bands, lateral bands not developed. _ It seems 

 that this particular form is common in Belgium, and it may be 

 supposed that it reached America with garden plants from that 

 country. T. D. A. COCKERELL.
