Remarks. — Fotuid from Xew Jersey to Rio Janeiro, in Brazil. 

 This species was recorded from Great Egg Harbor, in Xew 

 Jerse}', by Leidy, in 1855. The example described above was 

 secured at Holly Beach by Mr. J. E. Ives, in 1890. It is a male 

 and dried, also faded nearly uniformly whitish. It is smaller 

 than recorded dimensions, males being known 46.5 mm. long and 

 103.6 mm. wide. 



I have also examined similar small examples to the one de- 

 scribed above from Cape ^lay and Absecon. In the summer of 

 1908 I obtained it at Ocean Citv in small numbers.
