LIST OF SHELLS OBTAINED BY MR. LUDWIG KUMLIEN, NATURALIST TO THE HOWGATE 

 EXPEDITION, 1877-78, AT POINTS IN CUMBERLAND SOUND, ARCTIC REGIONS, WEST 

 FROM BAFFIN'S BAY. 



BY W. H. DALL. 



The locality at which the schooner Florence, conveying the party, 

 made her winter quarters, according to Mr. Kumlien's report, was not 

 favorable for extensive collections in any department. 



The prevalence of ice in the irregularities of the sound and other cir- 

 cumstances, especially the abrupt and rocky character of the shores, 

 rendered it difficult to obtain specimens of invertebrates, which in point 

 of fact were all collected at a few small areas of beach, some of which 

 were a Jong distance from winter quarters. 



Nevertheless, when the difficulties are considered, the results are very 

 creditable to Mr. Kuinlien's energy and perseverance, and are not with- 

 out value for the study of geographical distribution. 



The number of specimens is small 5 but twenty-four species are repre- 

 sented, some of which were also obtained by a party under Lieutenant 

 Mintzer, U. S. X., who explored for minerals in nearly the same region 

 a year or two previous to the visit of the Florence. 



As was to be expected, none of the species are new: Modiolaria faba 

 Fabr., which has almost been lost sight of by naturalists, and Glyci- 

 meris Kurriana Dkr., a species whose validity has been much questioned, 

 were among the most interesting forms obtained. 



The species are as follows (those with an asterisk are represented by 

 only one or two specimens, and only Buccimim gronlandicum was at all 

 numerous) : 



*0mmast replies illecebrosa, Lesueur. 



* Buccinum ylaciale, Linne. 



* Buccimim ciUatum, Fabr., var. Molleri, Eve. 



* Buccinum humphreysianum, Bennett (probably). 



* Buccinum lelcheri, Eve.
