Munididae indet.

Fig. 23 .

Material.—Various fragments, including ventres, meri, and propodi, GPIBo 92, 93, 101–105, NRM-PZ Ar68002

(2 fragments), NRM-PZ Ar68003 (2 fragments), NRM-PZ Ar68005 (4 fragments), NRM-PZ Ar68006 (6 fragments), NRM-PZ Ar68008+680014 (5 fragments), NRM-PZ Ar 68009, NRM-PZ Ar68010, NRM-PZ Ar68011, NRM-PZ Ar68012, NRM-PZ Ar68013, NRM-PZ Ar68015. From the upper Paleocene of Zachariassendalen ( NRM-PZ specimens) and locality 500 m west from Trigonometric point 25 ( GPIBo specimens), Hollendarbukta, Spitsbergen, Svalbard.

Remarks.— Gripp (1927) and Vonderbank (1970) ascribed a variety of isolated appendages and venters to what they considered to be P. spitzbergica , but because there are two galatheoid species in the region, those cannot be ascribed to any taxon with certainty. None of those specimens were attached to carapaces. It is likely, however, that most, if not all, can be attributed to Valamunida haeggi Klompmaker and Robins sp. nov. because 15/16 carapaces studied are ascribed to this species and appendages are found in the same rock as some of the carapaces for the ones found in Zachariassendalen ( NRM-PZ Ar68002, NRM-PZ Ar68003, NRM-PZ Ar68006, and NRM-PZ Ar68010/Ar68013).
