worthy of being mentioned, however, can be said to have been 

 placed upon record until the appearance of the list of Dr. H. 

 Dohrn, in the 16th volume of the c Malacozoologische Blatter,' 

 in 1869, where no less than 29 species were carefully and 

 systematically enumerated. These 29 members, chiefly of the 

 Pulmonobranchiata, although including a few which had been 

 collected by the Eev. K. T. Lowe and myself in January and 

 February of 1866, were chiefly due to Dohrn's personal re- 

 searches amongst the islands in 1864 and 1865 ; and had it not 

 been for an unlucky accident in the after-loss of the greater 

 portion of his material, the number might perhaps have been 

 still further increased. 



The next, and latest, resume of the Land- Shells of the 

 Cape-Verdes was given by Morelet in the 13th volume of 

 Crosse's 'Journal de Conchyliologie,' in 1873. It was while 

 noticing a few additions to the catalogue which had recently 

 been made by MM. Bouvier and de Cessac that Morelet took 

 the opportunity of calling attention to the species which had 

 been observed, up to that date, in the whole archipelago ; and, 

 judging from his list which is now before me, he seems to have 

 brought up their number to 40. Although he speaks of eight 

 of them as having been contributed by MM. Bouvier and 

 de Cessac, it appears to me that eleven are alluded to which at 

 all events had not been cited by Dohrn, namely 



Helix Bouvieri, Morelet Pupa umbilicata (var. ancono- 

 armillata, Lowe stoma, Lowe) 



primseva, Morelet Achatina lubrica (var. maderen- 

 atlantidea, Morelet sis, Lowe) 



Draparnaldi, Beck Carychium minus, Per. 



Bulimus ventricosus, Drap. Melampus flavus, Gmel. 



Stenogyra decollata, Linn. 



Out of these, however, the ' var. anconostoma 5 of the Pupa 

 umbilicata, Drap., I have rejected, as being referable more 

 probably to the very closely allied (and perhaps scarcely distinct) 

 Pupa Dohrni, Pfeiff. ; as well as the Helix Draparnaldi, 

 Beck, as having been established on evidence which is not suffi- 

 ciently trustworthy. Moreover the Bulimus ventricosus and 

 Achatina lubrica are not very satisfactory additions to the 

 fauna, inasmuch as Morelet does not mention either in which 

 islands they were found or by whom ; nor indeed is there a 

 syllable said about the Carychium minus which figures in his 

 list, and which may perhaps therefore have been inserted on 

 nothing more than the original authority of Ferussac, in whose 

 long-discredited article (Bulletin Universel des Sciences et de 

 ^Industrie-, 1827) the species was mixed up with others the
