SCIENTIFIC RESULTS OF EXPLORATIONS BY THE U. S. FISH COMMISSION STEAMER ALBATROSS. [Published by permission of Hon. Marshall McDonald, Gomniissioner of Fislieries.] No. XXXII.— REPORT ON THE CRUSTACEA OF THE ORDER STOMATOPODA COLLECTED BY THE STEAMER ALBATROSS BETWEEN 1885 AND 1891, AND OX OTHER SPECIMENS IN THE U. S. NATIONAL MUSEUM. By Robert Payne Bjgelow, Ph. D., Bruce Fellotc in the Joints Hopkins Universiti/. The material which forms the subject of this report is derived from various sources. It consisted at first of the Stomatopoda collected by the Albatross on her voyage around to the Pacific during the winter of 1887-'88, This had been referred to Prof. W. K. Brooks for a report, and it was at his re([uest that I undertook the task. Subsequently the later collections-of the Albatross were turned over to me, including-the specimens collected during the expedition of 1891 uuder the direc-tion of Dr. Alexander Agassiz. The Crustacea of that expedition had been referred to Dr. Walter Faxon, and I am indebted to hiin for the Stomatopoda. I have had, moreover, free access to the collection of Stomatopoda in the U. S. National Museum, including the earlier collec-tions of the Albatross, specimens collected by the U. S. Fish Commis-sion schooner Grampus, and specimens sent in by naval officers and others. Many of these specimens had already been identified by Mr. Richard Rathbun. I have l)eeii able to make also a small addition to the collection, consisting of four species collected by me in the Bimini Islands, Bahamas, while there, during the summer of 1892, in connec-tion with the marine laboratory of the Johns Hoi^kins University. The collection as it now stands before me consists of adults and larvre, the former representing 34 species, distributed through 5 genera, as follows: Gonodactylus, 2; Odontoilactylas, 2; rseudosquilla, G; Lysio-squilla, 5; and Squilla, 19. Of all these 11 are new species. They com-prise inhabitants of tropical and temperate waters of both hemis-l)heres. The collection of larvte is large, but it contains nothing like a complete series of stages of any one species and almost no larva that can be referred with any certainty to its adult form.
