Ludwig Pfeiffer, in the second volume of his Monographia Heli- 

 ceorum Viventium * assigns Bulinus maculiferus Sowerby to Bulimus 

 per versus Linnaeus, as variety E, but a year later 2 changed his opin- 

 ion and considered it a valid species. In the above work he gives a 

 full description of this species (p. 134), and Bulimus chloris Reeve 

 (p. 137), citing a variety B of the latter, and giving the Philippine 

 Islands with Cuming as authority for the habitat of A. chloris Reeve. 



In the part on Mollusca, of the Zoology of the Voyage of H. M. S. 

 Samarang, 1850, by Arthur Adams and Lovell Reeve, the following 

 statement is found (p. 58) : "The animal of Bulimus chloris is of a 

 pale brown color, always differing in this respect from that of B. 

 citrinus, and of extremely vivacious habits. A bushel of them, col- 

 lected on the mountains of Mindanao, soon dispersed themselves all 

 over the cabin in which the basket was deposited. The shell was of 

 the same elongated form and deep yellow color throughout, with no 

 indication of bands or markings." 



The same year Johan Christian Albers erected the genus Amphi- 

 dromus 3 placing in it, among others, the two species A. maculiferus 

 Sowerby and A. chloris Reeve., heretofore referred to. 



Pfeiffer, in 1853, 4 retains Bulimus for the group. He redescribes 

 (p. 319), B. maculiferus Reeve and adds a description of var. @, 

 which in the present effort is referred to as A. maculiferus gracilior 

 Fulton, and another form y, which we consider synonymous with A. 

 maculiferus as from Mindanao. He also relists Bulimus chloris 

 Reeve as in volume 2. 



In 1854 Jacques Bernard Hombron and Honore Jacquinot pub- 

 lished the Molluscan part of the Voyage au Pole Sud et Dans 

 L'Oceanie of the Astrolabe and Velee. 6 On page 29 of this work 

 Bulimus sulphuratus is described from Samboanga. It is figured on 

 plate 8, figures 10-12. This has since been placed in the synonomy 

 of Amphidromus chloris Reeve. 



In 1855, Pfeiffer's Monograph on the genus Bulimus was pub- 

 lished. 6 In it, on pages 117-118, Btdimus maculiferus is described, 

 and figured on plate 36, figures 1 and 2, and a variety [3 on plate 40, 

 figure 9, which has since been described as Amphidromus macu- 

 liferus gracilior by Fulton. 



In the same volume (p. 183), Bulimus chloris Reeve, is described 

 and figured on plate 49, figures 7 and 8, and Bulimus sulphuratus, 

 Hombron and Jacquinot is placed in the synonomy of it.
