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.

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. It does cou-
