C.l (Packard), BlufTton, S. C! (Dr. Mellichamp), Key West! 

 (Packard), Aspinwall I (McNiel), Long Island Sound and Baha- 

 mas (Smith), Cuba (Martens), Rio Janeiro (Heller). According 

 to Mr. Faxon there are specimens in the Museum of Comparative 

 Zoology from Boston (Gould?, 1853) and Providence River, R. I. 



Panopeus packardii Kingsley. 



Panopeus packardii Kingsley, Proc. Bost. Soc'y, xx. p. 152. 



Specimens occur from Sarasota Bay, Harbor Key, and Charlotte 

 Harbor, Fla. The majority of these specimens have the sinus 

 between the angle of the orbit and the second normal tooth more 

 shallow than did my types, which were from Key West (Packard). 



Panopeus texanus Stimpson. 



Panopeus texanus Stm., Ann. Lye., vii. p. 55. 

 Panopeus sayi Smith, Proc. Bost. Soc'y, xii. p. 284. 



Specimens occur in the Union College collection from North- 

 ampton Co., Ya., Beaufort, N. C, and Sarasota Bay, Fla. I have 

 also seen specimens from Eastham, Mass. (W. C. Fish), Wood's 

 Holl, Mass. (Packard, Verrill), New Haven, Conn. (Yale College). 

 A careful examination of a lai'ge series has led me to unite these 

 two forms, as I cannot find constant differences to separate them. 

 There is all variation in the subhepatic tubercle, from one as 

 prominent as typical specimens of P. herbstii to complete absence; 

 the form of the anterolateral teeth varies, while the terminal seg- 

 ment of the male abdomen is the same in each form; in some the 

 fingers of both hands were slender, some had them pointed on one 

 hand and excavate on the other, while others had the fingers of 

 both hands excavate. I am the more ready to unite them since 

 Prof. Smith suggests their possible identity. 



Panopeus depressus Smith. 



Panopeus depressus Smith, Proc. Bost. Soc'y, xii. p. 283; Fi9h Com.,
