«PECTEN ACUTICOSTATUS.
Fig. 18. P. testâ suborbiculari, valvâ alterâ convexâ, costis radiantibus 20, acutis, elevatis; lateribus costarum interstitiisque concentricè striatis; auriculis magnis, tenuiter radiatim costatis.
A fragment only of one valve of this species has been found; it will however easily be distinguished from the numerous species of this genus by its elevated triangular ribs, broader at their base than the interstices.»
