 Royal Dublin Society. vol. 1 l|. iMO, pi."), ligs. li. S 11) from Beechey 

 l-land -pirimens. In the list of fossils which H. M. AMI has published in 

 Low's report on the Arctic voyage of the "Neptune" (Ottawa 1906) Loxo- 

 ))i'ind rossi is ([noted, p. 3:20, from a bluish grey limestone of the same 

 locality. In a collection in IVabodv Museum in New Haven I have had 



** 



an opportunity of examining specimens of this form, (labelled by Dr. AMI). 

 and 1 have found them to be extremely similar to the specimens nd- 

 Irrted by SCHKI. A certain conclusion as to the identity of the forms. 

 however, cannot be made with no better preserved material that which 

 i- now in my possession. 



The specimens in the collection attain a maximum length of 13 

 1 \ mm. but are usually much smaller. The most complete ones show 

 about 9 volution-, yet originally there were still more. The height of 

 the volutions is about two thirds of the greatest width. In one specimen 

 with partially preserved surface an indication of a longitudinal band on 

 the lower volutions can be seen, showing that the form is no Loxo- 

 urmtt. but probably belongs to Horutotonia. 



Occurrence: B, lower part, Reindeer Valley.

 of about the >ame age. Amongst others come into consideration the

this form is named Ln.roncnm Hultcri. It is reported to occur together 

 with Atri/i><i II/KK-H on (iornwallis Island, in Assistance Bay. and on the 

 We-l ma>l of lloolbia Felix. It is necessary, however, to see the speci- 

 men or a heller illustration than SM.MK'.X old one before classifying this 

 species with certainty. 



Occurrence: 13, lower part, Keindeer Valley.
