? Triadocypris sp. ( Van Veen 1936) (new combination)

Fig. 4 C

Cypridina spec. Van Veen 1936:170, pl. 9: fig. 22.

Material

No material examined herein.

Diagnosis

Elongate rostrum with rounded tip; ventral margin of rostrum forms acute angle with anterior margin of valve ventral to rostrum. Central adductor muscle scars unknown.

Remarks

Only a single anterior part of a left valve is present in the Van Veen Collection. The species is questionably referred to Triadocypris because the posterior part of the valve is missing, so that it is not known whether it is evenly rounded or angular.

Comparisons

Rostrum more elongate than that of M. hollandica .
