Notes on marine fishes from the Netherlands Antilles, with the description of a new species, Eutyx tumidifrons (Brotulidae)

A small number of fishes from the Netherlands Antilles has been collected and recently presented to the Leiden Museum by Dr. J. S. Zaneveld, Head of the Biology Department, College of William and Mary, Norfolk, Va., formerly Director of the Caraibisch Marien Biologisch Instituut, Curaçao; and Dr. L. B. Holthuis, Curator of Carcinology at the Leiden Museum. While most specimens proved to belong to known Caribbean Syngnathidae, one very remarkable specimen appeared to belong to an undescribed species.
