no. 3641 STOMATOPOD CRUSTACEA — MANNING 3 



Crosnier (1965) listed Squilla nepa and S. raphidea as occurring 

 among catches of penaeid shrimps off Madagascar; the latter species 

 is probably Harpiosquilla harpax. 



In a review of the genus Odontodactylus, Manning (1967a) recorded 

 the occurrence of two species, 0. japonicus (de Haan) and 0. scyllarus 

 (Linnaeus); those records were based on three specimens reported 

 below. 



Manning (1967b) reported Gonodactylus lanchesteri Manning from 

 the Comoro Islands ; none of the seven species of Gonodactylus included 

 in that study were from Madagascar proper. 



Explanations and acknowledgments. — In general, synonymies 

 are shortened, including only major references and some recent 

 pertinent references; original citations, if made by Kemp (1913), are 

 not repeated here. Where applicable, reference is made to Kemp's 

 1913 monograph of the Indo-West Pacific stomatopods. 



In the section "Previous Kecords," earlier records of the occurrence 

 of each species on Madagascar are summarized. For the species not 

 illustrated herein, a figure to aid identification of the species is cited 

 under the paragraph entitled "Illustration." 



Measurements are given in millimeters (mm). In the material 

 examined, the numerals following the number of specimens denote 

 total length (TL), unless carapace length (CL) is specified; the latter 

 is given only for damaged specimens. Total length is measured along 

 the midline from the apex of the rostral plate to the apices of the sub- 

 median teeth of the telson. Carapace length is measured along the 

 midline and does not include the rostral plate. 



An abdominal spine formula of "submedian, 5-6; intermediate, 

 2-6; lateral, (1) 2-6; marginal, 1-5" indicates that the submedian 

 carinae of the abdomen terminate in spines on the fifth and sixth 

 somites, the intermediate carinae terminate in spines on the second 

 to sixth somites, inclusive, the lateral carinae always terminate in 

 spines on the second to somites, but these carinae occasionally are 

 armed on the first somite, and all five marginal carinae terminate in 

 spines. A parenthesis is used to indicate that a carina on a certain 

 somite may be unarmed. A telson denticle formula of "5, 7-10, 1" 

 indicates that on the telson margin, on each side of the midline, there 

 are five submedian denticles, seven to 10 intermediate denticles, and 

 one lateral denticle. The count of teeth on the dactylus of the claw 

 always includes the terminal teeth. 



The corneal index (CI) is calculated as carapace length/cornea width 

 X 100. 



Most specimens, including all holotypes, have been deposited in the 

 Division of Crustacea, Smithsonian Institution (USNM); an identi-
