NO. 9 manning: Atlantic stomatopod Crustacea 5 



spines on the fifth and sixth, and so on. A denticular formula of 1-3, 

 (4)5-7(8), 1 indicates that there are one to three submedian denticles, 

 four to eight, usually 5-7, intermediate denticles, and one lateral den- 

 ticle. 



The generic key is largely that of Schmitt (1940). The specific 

 keys include all of the species heretofore reported between Panama and 

 Recife, Brazil. One species reported from southern Brazil by Lemos de 

 Castro (1955) (Lysiosquilla excavatrix Brooks) is also known from 

 the southern United States but has not been been collected from inter- 

 mediate areas and this species is not included in the keys. 



The initials AHF (Allan Hancock Foundation), UM ML (The Ma- 

 rine Laboratory, University of Miami), or USNM (U. S. National Mu- 

 seum) after each lot of material indicate where that material will be 

 deposited. 



In the "material examined" sections under each species, stations 

 such as "A 14-39" are Allan Hancock Foundation stations. "A" refers 

 to the Atlantic stations, and "-39" indicates the year. 



I am indebted to Dr. John S. Garth of the Hancock Foundation for 

 placing the stomatopod material of the Allan Hancock Atlantic Expedi- 

 tion at my disposal ; Harvey R. Bullis, Jr., Base Director, South Atlan- 

 tic Exploration and Gear Research, U. S. Fish and Wildlife Service, 

 for making available material collected by the U.S.F.W.S. research ves- 

 sels; Dr. Fenner A. Chace, Jr., Curator, Division of Marine Inverte- 

 brates, U. S. National Museum, for supplying comparative material, 

 for providing working space at Washington, and for his comments on 

 the manuscript; Dr. L. B. Holthuis, Rijksmuseum van Natuurlijke 

 Historie, Leiden, for his comments on several systematic problems; 

 Dr. Gilbert L. Voss, Curator of Marine Invertebrates, The Marine Lab- 

 oratory, University of Miami, for reviewing the manuscript. This work 

 was carried out with the support of the National Science Foundation, 

 under Grant No. G-11235, and constitutes a technical report to that 

 organization.
