heads of this description have come under my notice, showing 

 that the difference in the size of the horn does not always amount 

 to a deformity. 



In a note to an article published in the Zoologist for March, 

 1904, Mr. A. Heneage Cocks records the following : ' I have 

 never seen the fact noticed that the right eye of young mammals 

 opens before the left. I do not remember an exception among 

 wild animals, nor even among domestic animals, though it is 

 very likely some occur in the latter class. From the time the 

 lids of the right eye begin to part to the time the left eye is fully 

 opened takes generally from thirty-six to forty hours." Com- 

 menting on this the editor of Knowledge remarks. " The fact 

 is as new to us as it is to Mr. Cocks, and requires an explanation. 

 The suggestion naturally occurs that the phenomenon is con- 

 nected with ' right-handedness ' in the human species." 



It would be interesting to discover whether stags, when 

 fighting, use the right and left horns indiscriminately, or whether 

 thev endeavour to strike with one horn more than the other. 



Art. XXXIII. — A New Placostylus from New Zealand. 



By Henry Suter. 



[Rend before the Wellington Philosophical Society, 2nd October, 1907.] 



Plato XXV. 



Many years back, when reading Dr. A. Lesson and Martinet's 

 " Les Polynesiens," I came across, in vol. iv. (1884), p. 227, the 

 following passage, of which I made a note : " Le Bulimus hongi, 

 Pupuharakeke, se trouve surtout pres du cap Nord ; il y abonde 

 parmi les Phormiums. Cette belle coquille est de couleur 

 chocolat fonce, avec l'interieur blanc ou orange brillant ; elle 

 a pres de 4 pouces de long. On dit que le Bulimus vibratus 

 abonde sur les Trois Rois." 



When Captain J. Bollons told me last autumn that he had 

 to visit and stay for several days at the Great King Island, 1 

 asked him to be good enough to have a search made for specimens 

 of Placostylus, if time would permit it. How great was my 

 joy when in the middle of April, 1907, he brought me a number 

 of living and some empty specimens of a large and distinct 

 Placostylus he had been successful in finding under dead leaves 

 on the Great King Island. I was prepared for a form similar 

 to that found at Cape Maria, van Diemen, but certainly not 

 for such a distinct new species. My very best thanks are due
