Sowerby I 1843c : 123, pl. 27, fig. 131 [June]. Pfeiffer 1846 : 14, pl. 8, figs 1, 2. Cyclophorus aquilus - Reeve 1861 : sp. 45. Kobelt 1902 : 124. Kobelt 1907 : 578. Type locality. Singapore. Type material. Lectotype (design. n.), NHMUK 20110225/1 ( Fig. 3E; D =39.9 mm, H=31.7 mm, W=5), paralectotypes NHMUK 20110225/2-3 (2 shells; Fig. 3F; D =38.7 mm, H=29.5 mm, W=5, and D=39.9 mm, H=31.2 mm, W=5). Remarks. A figure was not provided in the original description but a figure in "Thes. Conch. part 3, pl. 27, fig. 131" was cited. The original description states 'Found in the Woods at Singapore under decayed leaves by H. Cuming' . There are three specimens from the Cuming collection with an original label, possibly in Sowerby's handwriting that states 'Singapore in the wood under decayed leaves' . We therefore recognize these specimens as syntypes and the figured specimen ( Sowerby I 1843c : pl. 27, fig. 131) is here designated as the lectotype.
