CRITICAL EXAMINATION OF CERTAIN SPECIES OF 

 THE AMERICAN CONTINENT, AND THE WEST INDIES, 

 DESCRIBED AS BELONGING TO HELICINA IN LOVELL 

 REEVE'S CONCHOLOGIA ICONICA. 



By T. Bland. 



(Abridged translation from the Journal de Concliyliologie, by C. P. Gloyni.. ) 



The genus Helicina as understood by Reeve includes Lucidella, 

 Trochatella, Helicina, Schasicheila, and Alcadia of other authors. 



The number of errors in Reeve's Monograph is truly astonishing. 



A mere compiler, totally ignorant of the subject, could have 

 avoided the greater part of them with a little care: — some examples 

 will be given. — 



Helicina Bayamensis and Bastidana are considered as separate 

 species under the names of H. Bayhamensis and Bastidiana ; Poey, 

 the author of these two names has himself acknowledged that the 

 second is only a variety ot the first. 



H. Catalinensis, so called from the locality Catalina in Cuba, is 

 called H Catiliniana as if it were dedicated to one Mr. Catilini, 

 and Pfeiffer's original description is given in the synonymy, and 

 stated to be from Blainville's Malacology instead of the Malako- 

 zoologische Blaetter [Doubtless Reeve saw "Mai. Bl." and made a 

 guess at the meaning of the abbreviation]. 



H littoricola, Gundlach, from Baracoa, Cuba, with the figures of 

 some other species, is mentioned as H. littoralis of Baraccas. 



H. nuda, Arango, is figured under the name of H Nodce, Gund- 

 lach, and with the habitat "Arango" [M. Crosse pleasantly remarks 

 in a foot-note that this is not taking the Pirceus for a man, but a 

 man for the Piraeus]. 



H arenicola Morelet, of Yucatan is attributed to one Morton, 

 whoever he may be, and is wrongly stated to come from Cuba. 



H orbiculata, Say, is attributed to Sowerby. 



The errors of habitat are quite unpardonable. The following 

 are corrections, Reeve's wrong locality being given first and the 

 right one afterwards : — H virginea, Lea, Cuba, should be Haiti. 

 H. minima, Orb., St. Thomas, Cuba and Bahamas. H. platycheila 

 Muhlf , Cuba and Martinique, Martinique only. H. substriata. 

 Gray, Cuba, Barbadoes. H. Chittyana, Pfr., Cuba, Jamaica. H. 

 rugosa, Pfr., Island of Trinidad, Trinidad in Cuba. H. vernalis, 

 Mor., Cuba, Guatemala.
