NO. 8 HAIG : THE ATLANTIC GALATHEIDEA 31 



portion of the carapace is wider than the anterior portion, and the 

 median tooth of the front is much shorter than the two preorbital ones. 

 The specimen of M. angustus reported by Rathbun (1900) lacked this 

 median tooth entirely, and in her opinion it had been broken off and not 

 renewed. 



Aside from P. rosamondae, which is probably this species, Minyo- 

 cerus angustus has previously been reported only from Brazil.
