Dimensions.

"Long. 63, diam. 33 mm.". Figured specimen H 62.6, D 36.6, W 5.9.

Type material.

NHMUK 1907.11.21.114, lectotype (da Costa coll.).

Remarks.

da Costa did not state on how many specimens his description was based; the reference in Breure and Schouten (1985) to "HT BMNH 1907.11.21.114" has to be interpreted as lectotype designation under Art. 74.6 ICZN. The current systematic position follows Breure and Borrero (2008). However, it should be noted that Strebel (1909: 120)-after establishing the subgenus Oxyorthalicus -wrote "Die Skulpturbeschreibung [by da Costa] bezw. das Fehlen der erhabenen Streifen scheint mir für die Untergattung unwahrscheinlich". Further anatomical and molecular research should thus shed more light on the taxonomic position.

Current systematic position.
