Olig Atlas pl19-01 01-3.JPG
figured-specimen_1091.jpgCurrent identification/main database link: Streptochilus martini (Pijpers 1933)
Original Description
Species of small size, conical, compressed, with rounded sides. Initial end pointed, test regularly increasing in width, towards the apertural end, where it is widest. Wall smooth, finely arenaceous, with much cement. Sutures (except in the early portion) distinct, depressed. Course of the sutures rather varying. Chambers first gradually, later rapidly increasing in size; early chambers low and broad, later chambers higher. Aperture elongate, occasionally slightly curved, at the inner margin of the last formed chamber and perpendicular to that margin.
Etymology: The species has been named in honour of Prof. K. MARTIN
Extra details from original publication
The species has some resemblance with T. subagglutinans Cushman from the Miocene of Panama. T. subagglutinans differs by its truncated sides, by its wall being composed of rather coarse arenaceous material and by the shape of its aperture, being more rounded .
