Slightly like B. binneyanus Pfr., but differs markedly in sculpture, 

 and in the absence of a keel on the whorls of the spire. Reeve very 

 justly compares it to .B. lemnixcatus Desh., a species which is not 

 keeled, but is certainly nearly allied. 



Pfeiffer restored Gray's name to this species in the later volumes 

 of the Monographia because the date of presentation of Gray's de- 

 scription before the Zoological Society of London was prior to 

 Philippi's publication. Philippi's description, however, was actually 

 jniblished in the sense of being printed and distributed, first ; so that 

 under existing rules, which disregard the mere date of reading, the 

 name reentsi has precedence.
