Excerpt from The Decapoda of the Siboga Expedition, Vol. 1: Family Penaeidae The Penacidae collected by the Siboga Expedition ought to be considered as a most valuable contribution to our knowledge of these interesting animals and to the Fauna of the East Indian Archipelago. No less than 54 species and 2 varieties have been collected and of the species 19 or 20 proved to be new to science. Of the 34 or 35 already known species only 13 or 14 have been observed formerly in this Archipelago. The deep-sea investigations especially have been of great importance. A rather large number of species, viz. about 24, have been captured in the great depths and abysses of the sea, but of these species only 3 were already known to occur in the Archipelago, viz. Aristeus semidentatus (Sp. Bate), Haliporus neptunus Sp. Bate and Haliporus Lucasii (Sp. Bate), species collected formerly by the "Challenger." The genus Benthesicymus Sp. Bate is only represented by one species, but of the remarkable genus Gennadas Sp. Bate two species were obtained, both new to science, no species of Gennadas were hitherto known from the Archipelago, except Genn. Bouvieri Kemp, described only in 1909, a form observed West of Manila at 2100 fathoms and North of New Guinea at 1100 fathoms. Of the new Hemipenacus Sibogae a fine full-grown female was collected at a depth of 1000 meter. Very remarkable is the discovery of the -new Haliporus Sibogae, a species living at depths between 400 and 521 meters, and of which at four Stations more than 50 well preserved specimens, mostly adult, were captured: this interesting species belongs to the largest representatives of this genus, the male attaining a length of 165 mm., while the female becomes 175 mm. long. Halip. Sibogae appertains to a Section, that hitherto was still unknown in the Indopacific. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
