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

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

 FROM BAFFIN'S BAY. 



By W. H. Dall. 



Tlic locality at Aviiicli tlie schooner Florence, conveying the party, 

 made her winter quarterns, 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 long distance from winter quarters. 



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

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

 out value for the study of geographical distribution. 



Tlie luimber of specimens is small; but twenty-four species are repre- 

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

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

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



.Vs Avas to be expected, none of the species are new: Modiolaria faha 

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

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

 Avei-e auiong the most interesting forms obtained. 



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

 vnly one or two specimens, and only Biiccinum (ironhindicum was at all 

 numerous): 



* Ommastrcphcs illecehrosa, Lesueur. 



* Buccinum glacialc, Linnci. 



* lluccininn cillatum, Fabr., var. Mollcri, live. 



* Ihiccinuni liumphrcysianum^ Uennett (i^robably). 



* Buccinum helcheri, Rve.
