64 SMITH : RECENT SPECIES OF THE GENUS PIRULA, LAMARCK. 



His researches on the " Relations of the Cranial Nerves to the 

 Sensory Canal System " are published in the " Proceedings of 

 the Birmingham Philosophical Society," the British Association 

 Report for 1893, and are still appearing in the "Quarterly Journal 

 of Microscopical Science." 



Mr. CoUinge is thus not a faddist in Conchology — but a sound 

 scientific student of Anatomy, who has long been specially interested 

 in this branch of it. Doubtless anyone's interest in '' Snails " 

 begins with his pleasure in contemplating the spiral covering, but 

 it is mere dilettanteism and not science to end as a collector of 

 shells for one's cabinet. In the " Conchologist " Mr. Collinge has 

 always acted liberally in publishing freely the views of enthusiastic 

 collectors, but his personal contributions to the subject are mainly 

 anatomical, and it is on the anatomy mainly that he relies for 

 identification of species, or for establishment of relationship. 



I understand that Mr. Collinge has in MS. the first of a 

 series of studies in Vertebrate Morphology. Text-books on types 

 become after a time %ome\\\\Vit polarized ; and if for no other reason 

 new books on new selected types should be made welcome. But, 

 although somewhat unkind to prejudice unseen work, we may expect 

 from Mr. Collinge something better than mere text-books on typical 

 animals, which' may replace our present dog's-eared copies.
