OF CONCHOLOGY. 149 



the shell, the latter is of course not " hairy ; " in other words, 

 every character which is not common to almost all forms decidedly 

 opposes the identification of Dr. Gray, and we can only suppose 

 that the gentleman completely ignored the description and 

 identified it by means oi i^art of the name, overlooking that part 

 which negatived it ! 



It has been deemed advisable, in view of the perfect concord- 

 ance of Browne's notice with young specimens oi S. canaliculatvs, 

 to retain his name for the genus, but had another been given to 

 it, we should not have felt justified in so doing. As Sijcotypus 

 of Gray is merely a synonym of Pyrula, Lam., no existing genus 

 bears the name, and although in most cases the employment of 

 names that have already been used in another sense is inadvisa 

 ble, in this it may be justifiable. 



The following species are members of the genus Sycotypus. 

 The S. canaliferus, jS. incilis and S. aheatKS, are not at present 

 accessible for autopsy and are adopted solely on the authority of 

 Mr. Conrad. To the list of doubtful related species must be 

 added the Cassidulus Conradii, Tuomey and Holmes, (Plioc. 

 Fossils S. C, p. 147, pi. 29, f. 4).
