Orthalicus mars Pfeiffer, 1861 Figs 13v-vi, L13i

Orthalicus mars Pfeiffer 1861b: 25, pl. 2 fig. 8; Pfeiffer 1868b: 202; Pilsbry 1899: 143, pl. 53 fig. 42.

Type locality.

"republica Aequatoris (Mr. Fraser)".

Label.

"Republic of Ecuador", taxon label in Pfeiffer’s handwriting. M.C. label style IV.

Dimensions.

"Long. 77, diam. 35 mill.". Figured specimen H 76.6, D 38.4, W 6+.

Type material.

NHMUK 20100504, three syntypes (Cuming coll.).

Remarks.

Pfeiffer did not state on how many specimens his description was based, but described "from the collection of H. Cuming". Although on the label has been written in a later hand "none quite like fig.", the type status is not disputed as the shell height matches the original data. The top of the largest specimen, herein figured, is damaged. Also the top of one of the other specimens is damaged. The protoconch of the third, undamaged, specimen is smooth. This taxon is tentatively classified with Orthalicus Beck, 1837; however, further anatomical and molecular research should provide evidence to assess if this classification is correct or needs to be adjusted.

Current systematic position.
