Amphidromus maculiferus gracilior Fulton, 1896

Bulimus maculiferus var. β. Pfeiffer, 1853: 319. Küster and Pfeiffer 1854: pl. 40, fig. 9.

Amphidromus maculiferus var. gracilior Pfeiffer, Fulton 1896a: 74, 75.

Type locality.

Mindanao Island [Philippines].

Type material.

Possible syntype NHMUK 1842.5.10.60 (1S, Fig. 8I; H=56.3 mm, W=28.8 mm).

Remarks.

Fulton (1896a: 74, 75) attributed the authorship of this species to L. Pfeiffer. However, “Gracilior” in Pfeiffer (1853: 319) is only the first word of the description which is not a valid name ( ICZN 1999: Art. 11.9). Therefore, Fulton (1896a: 74) is the sole author of this species.

The specimens that Pfeiffer used as the basis for " Bulimus maculiferus var. β.”, were examined and used by Fulton, and are acknowledged as the type series ( ICZN 1999: Art 72.4). A single specimen in the NHM from H. Cuming’ s collection with Fulton’s handwritten labels bearing the taxon name and the locality "Mindanao, Philippines" is considered to be a possible syntype. This specimen corresponds closely with the figure in Küster and Pfeiffer (1854: pl. 40, fig. 9). However, the specimen is much smaller in size than the specimens quoted in Pfeiffer (1853: 319). Therefore, we treat the NHM specimen as a possible syntype.
