“Hyalopecten, gen. nov. Type, H. undatus V.
PLATE XVIII. fig. 5.
Shell compressed, thin, hyaline. Valves nearly equal, with concentric undulations or corrugations, affecting the entire thickness; margins simple; sculpture none, or consisting of fine radial lines on one or both valves, without camptonectes sculpture. Hinge-plate thin and nearly plain; auricles well developed, unequal; byssal notch distinct.
The possible relations of this group to Syncyclonema were discussed on page 63.
The species known to me are as follows: H. dilectus V. and B., from 1813 fath., off Martha's Vineyard; H. fragilis (Jeff.), from northern Europe and the Arctic Ocean, and off the U. S. coast, in 578 to 1525 fath.; H. undatus Ver., off the U. S. coast, in 1423 fath.; and H. pudicus Smith, off Marion I., in 1375 fath.”

Hyalopecten is a genus of marine bivalve molluscs.
The placement of the genus Hyalopecten is currently uncertain. Habe[1] included Hyalopecten within the subfamily Camptonectinae. However, Hyalopecten lacks antimarginal microsculpture, which is a key characteristic of Camptonectinae.[2] Some authors consider Ciclopecten Seguenza, 1877 to be a senior synonym, however Ciclopecten has antimarginal microsculpture.

Hyalopecten est genus marinorum molluscorum bivalvium familiae Pectinidarum.
Circumscriptio generis hodie est incerta. Habe[1] Hyalopectinem intra subfamiliam Camptonectinas ponit; genus autem microsculptura antimarginali, gravi Camptonectinarum proprietate, caret.[2] Aliqui auctores putant Ciclopectinem (Seguenza, 1877) maius synonymum; Ciclopectini autem est microsculptura antimarginalis.
Haec stipula ad bivalve spectat. Amplifica, si potes! Hyalopecten est genus marinorum molluscorum bivalvium familiae Pectinidarum.
