THE NAUTILUS. 59 



chology " that several of his genera are " for the first time pub- 

 lished" in that work (the text of which probably was written first), 

 yet some of them actually appeared in print a year earlier in his 

 short-lived journal called the "Arcana." Among these was Septa, 

 which appeared in connection with the single species Murex rubecula 

 Linne, which of course must be taken as the type. Perry's idea of 

 his genus doubtless was that it covered the species called Triton by 

 Lamarck, and so, in intent, it is a synonym of Cymatium Bolten, 

 1798. On account of the character of the type however, it might be 

 retained as a section for the species I formerly ranked under Lam- 

 pusia Schumacher, 1817. 



The first name available for the group typified by Murex tritonis 

 L. seems to be Nyctilochus of Gistel, 1848, and if, in accordance 

 with usage, we take this as the typical genus of the family, the 

 family name would be Nyctilochidcz. The genus Aquillm Montfort, 

 1810, upon which the family name was based by Dr. Pilsbry some 

 years ago, is unfortunately synonymous with Cabestana Bolten, 1798, 

 and therefore cannot be used. 



NOTES. 



POLYGTRA PALLIATA SAY IN NEW ENGLAND. The occurrence 

 of this species in New England has for a long time needed verifica- 

 tion. Repeated search in the Berkshires and Green Mountains by 

 the writer has failed to reveal its presence, although the other species 

 with similar distribution have been found. C. B. Adams, in Thomp- 

 son's History of Vermont, p. 159, 1842, says : " It is seldom found 

 in Vermont." W. G. Binney includes the species in the " Inverte- 

 brata of Massachusetts," but gives no locality. In July Messrs. 

 G. M. Allen and W. S. Brooks while trapping for small mammals 

 on Mt. Ascutney, Vt., obtained three specimens, one adult and two 

 young ; the latter were found feeding on the wet oat-meal used in 

 baiting the traps. It is somewhat surprising that this species should 

 turn up at last in this more isolated peak in the Connecticut Valley 

 and not in the Green Mts. proper, although there is little doubt but 

 that it will be found there with more thorough collecting C. W.
