NO. 3536 DECAPOD CRUSTACEANS — CHACE 



629 



Distribution : Indo-Pacific region from the Red Sea and Madagascar 

 to the Hawaiian Islands, littoral and sublittoral; St. Helena (new 

 Atlantic record). 



Synalpheus fritzmuelleri Coutiere 



Synalpheus fritzmulleri Coutiere, 1909, p. 35, fig. 18. 



Material: Off Rupert's Bay; buoy cable; 0-75 meters; Jan. 17, 

 1958; 1 male, 5 females (4 ovigerous).— Same; buoy; 0-2 meters; 

 Feb '2, 1959; 1 male, 2 ovigerous females.— Same; buoy and cable; 

 0-75 meters;' Mar. 18, 1960; 5 males, 20 females (11 ovigerous), 1 

 mutilated specimen.— Same; Apr. 5, 1962; 3 ovigerous females.— 

 Same- buoy; 0-2 meters; Feb. 11, 1963; 2 females.— James Bay; 

 collected by skindiver; April 1964; 1 male, 14 females (11 ovigerous). 



Measurements: Carapace lengths of males to base of rostrum, 3.2- 

 6.1 mm.; of females without eggs, 3.4-8.8 mm.; of ovigerous females, 



4.8-8.8 mm. 



Remarks : The St. Helena material agrees very well with the syntype 

 series of S. JritzmueUeri, with which it has been compared. Two or 

 three of the specimens are of the "oxyceros" form called S. JritzmueUeri 

 elongatus by Coutiere (1909), but most of them are of the typical form. 



As m S. senegambiensis (see Holthuis, 1951, p. 93), the males lack 

 both an appendix masculina and an appendix mterna on the endopod 

 of the second pleopod. In some of the specimens identified as females, 

 however, the appendix mterna is so slender that it is distinguishable 

 only with difficulty from the setae fringmg the endopod. 



Distribution : St. Helena (new record) ; western Atlantic from North 

 Carolina and Bermuda to Santa Catarina, Brazil; Baja California. 

 Littoral to more than 50 meters. The record of this species from 

 Greenland waters (Stephensen, 1950) is very questionable.

Material: James Bay; Jan. 29, 1964; 1 ovigerous female. 



Measurements: Carapace length in midline, 101 mm. 



Remarks: The uninterrupted transverse gi-ooves on all but the 

 first abdominal somites of this specunen caused me to believe at first 

 that it represented an undescribed, possibly endemic species. The 

 subsequent discovery in the national collections of a large male from
