In November 1974, Munidopsis bermudezi was 

 associated with M. curvirostra Whiteaves. Previ- 

 ous accounts did not indicate association of M. 

 bermudezi with other galatheids. Other decapods 

 taken in the November sample were Lithodes 

 agassizii Smith, Stereomastis sculpta (Smith), and 

 penaeidean and caridean shrimps, including 

 Hymenodora gracilis Smith, a species occurring in 

 the Azores sample (Sivertsen and Holthuis 1956). 



In September, M. bermudezi was associated 

 with M. bairdii (Smith) and M. crassa (Smith), as 

 well as Lithodes agassizii and caridean shrimp. 



The ovigerous M. bermudezi had not shed all 

 eggs onto the pleopods. The 19 external eggs were 

 tan and averaged 2.8 mm in diameter. These eggs 

 were spherical with no visible blastoderm and 

 were recently extruded. The ovary was tan and 

 very well developed. It contained 106 ova averag- 

 ing 2.7 mm in diameter. All eggs were measured 

 with an ocular micrometer. 



We suspect that these species with tropical 

 affinities are normally present, though rare, in 

 the Chesapeake Bight; but they could be acciden- 

 tal migrants. In either case, the probability of de- 

 tection was raised by the recent increase in sam- 

 pling intensity in the vicinity of Norfolk Canyon 

 as compared to other areas of the continental slope 

 between Florida and North Carolina. The question 

 of how far north the tropical fauna extends along 

 the southeastern coast of North America is still 

 unanswered (Briggs 1974). Cerame- Vivas and 

 Gray (1966) noted that the inshore fauna of the 

 North Carolina shelf was warm temperate 

 (Carolinian) but that the offshore fauna was tropi- 

 cal. In a study of sea stars of North Carolina, Gray 

 et al. (1968) found 13 species that occurred in a 

 northward extension of the Caribbean Province 

 along the outer shelf and that these species ranged 

 slightly northward past Cape Hatteras.
