an adaptive character, related to the breadth of the whorl, 

 almost all coiled Cephalopods which have wide whorls having 

 approximate septa and vice versd. 



Although therefore a new student of the Cephalopoda is to 

 be welcomed, as there is plenty of work to do, it would be 

 better that such a one should take up the story where others 

 have left it than go over the old ground with preconceived 

 theories and less careful observations. Nothing, in fact, in the 

 present communication is new ; though it may be little known, 

 it was all in print six years ago. 



I am not at all sure, however, that the suggestion to divide 

 the Cephalopods into three primary groups, Ammonoidea, 

 Nantiloidea, and Coleoidea, instead of into two, the Tetra- 

 braiichiata and the Dibranchiata, is not a good one. We 

 really do not know that the Ammonites were tetrabranchiate, 

 and by the old subdivision we assume they were. But 

 is Coleoidea a good name ? No doubt Sepia and Belemnites 

 have a " sheath," but has Spirula, or Loligo, or Octopus? 

 How would Belemnoidea do? The zoologists might not like 

 it ; but then it is more natural to name children after their 

 parents than vice versd. And from its relation to terms 

 already in use and its congruity with the other two every one 

 would know what was meant.

Transaction's of the CumherJand and Westmorland Association for 

 the Advancement of Literature and Science. No. xii. 1886-87. 

 8vo. Carlisle : G. and T. Coward, 1887. 



In this part of the ' Transactions ' of the local societies of Cumber- 

 land and Westmorland the contributions of purely literary and 

 antiquarian interest and those dealing with scientific subjects are 

 exactly in e(jual numbers. Of the former, although they are of con- 

 siderable general interest, we need saj- nothing here ; of the latter, 

 one is the "Zoological Record for Cumberland, J 886," by the Rev. 

 H. A. Macpherson and W. Duckworth, and the other bears the title 

 of " Our Summer Visitors," by Mr. Tom Duckworth, and is in con- 

 tinuation of previous communications by the same writer. The 

 former is a record of the occurrence and breeding of certain species 

 of birds in the district, to which are added notes on the habits of 

 several of the species and on some of the Mammalia of Cumberland. 

 In the latter we have a series of notes upon several of the birds 

 which visit the district in the summer — the Ring Oiizel, the "Wheat- 

 ear, the Nightjar, the Landrail, and the Common Sandpiper.
