THE UNIONID^E OF KANSAS, part I, by Richard E. Scammon, 

 (Kansas University Science Bulletin, iii, no. 9). " In this catalogue 

 are listed 61 species and 5 subspecies. There is no doubt that future 

 collecting will add many more species to the list. The author has 

 tried to make certain of the identification and localities of every 

 species listed, and with three exceptions has examined native speci- 

 mens of each." Nearly all of the species are illustrated by line 

 drawings occupying 23 plates, and all are described. Since only 

 about 40 species were previously known, it will be seen that one-third 

 of those now recorded are new to the state. Mr. Scammon proposes 

 two new descriptive terms : " interdentum" for that part of the 

 hinge-plate lying between the pseudocardinal and lateral teeth, and 

 " branchial outline" to designate the slight groove in the cavity of 

 the more solid Unios, caused by the edge of the branchiae. It is 

 proposed in future papers to discuss the geographic distribution and 

 soft anatomy of the species. 



NOTES. 



In a recent letter Prof. Josiah Keep says : " The principal part of 

 my edition of ' West American Shells ' was destroyed in the great 

 San Francisco fire, so there are no more copies in the book stores. 

 Fortunately the cuts were stored in my home, and may be used again 

 if there should be a considerable demand for a revised edition. Of 

 this matter, however, I do not feel certain, though I have received 

 some very kind letters upon the subject." We are sorry to learn of 

 Prof. Keep's great loss, and hope that he will receive sufficient 

 encouragement to undertake a new edition of his work. 



ZONITOIDES ALLIAR1A IN COLORADO A COUple of weeks ago 



Guy H. Mason found in the Knudson greenhouse, Boulder, Colo., a 

 specimen of Zonitoides alliaria Drap., a species well known to Euro- 

 pean conchologists, but of which American records seem to be rare, 

 and confined, so far as they have come to my attention, to green- 

 houses. It occurs to me that the rarity of records may have resulted 

 from American conchologists unfamiliar with the species placing it 

 in their collections under some other name, particularly Z. cellaria. 

 We are indebted to Dr. Wm. H. Dall for confirmation of the identi- 

 fication, he having compared it with British specimens as named by 

 Jeffreys. It was at once recognized by Prof. Cockerell as of that 

 species, but his long absence from Europe made him feel somewhat 

 uncertain about it without opportunity to make direct comparisons. 

 The specimen is now in the University of Colorado Museum
