Pecten testa suborbiculari fornicata, costis crebris convexis marginalibus muricatis, sulcis angustioribus in fundo plano profunde transversim striatis, auriculis aequalibus. — E montibus Baruthinis. M. M.
Dieser kleine Pectinit findet sich bei Streitberg. Er ist hoch gewölbt, gleichklappig, fast kreisrund und hat zahlreiche, convexe, gleichförmige Rippen, auf deren Rücken man bei der Vergrösserung stachelförmige Lamellen bemerkt. Die Zwischenfurchen sind concentrisch linirt, so dass sie ein punktirtes
Ansehen haben, und die Ohren klein und gleichförmig.» GEORG VON MÜNSTER, 1833

«2. AMENDED DIAGNOSIS
Distinguished from all other species of S. (Spondylopecten) by the number of plicae (27-36 or 37, see Section 4).
3. AMENDED DESCRIPTION
Essentially similar to S. (S.) palinurus. Differing by the diagnostic larger number of plicae (see Section 2) whose range and mode apparently oscillates phyletically (text fig. 86), by the evident possession of only 2 plical spine rows,and by the higher relative convexity (text fig. 84) of contemporaneous Oxfordian specimens and the lower relative convexity of Tithonian forms of S. (S.) subpunctatus in comparison with examples of S. (S.) palinurus from any horizon. Unlike S. (S.) palinurus, S. (S.) subpunctatus also exhibits phyletic reduction in L/UA (text fig. 85) although this could be more apparent than real (see Section 9).
H/L is plotted in text fig. 83. The maximum height is 58 mm (GEMMELLARO and DI BLASI, 1874).» JOHNSON, A. L. A. 1984. The palaeobiology of the bivalve families Pectinidae and Propeamussiidae in the Jurassic of Europe. Zitteliana, 11: 1-235, pls. 1-11. [p. 98, 99]
