a character which appears to be very variable. The three individ- 

 uals differ in this respect among themselves. 



Actaea setigera, Milne-Edwards. 



One male dredged off Shelly Bay. The individual differs from 

 the description given by Milne-Edwards (Notiv. Arch, du Mus. 

 d'Hist. ^a^., i, p. 271, pi. xviii, fig. 2) in having the color of the out- 

 side 01 the hands red, instead of black. It however agrees precisely 

 with specimens attributed to jNIilne-Edwards' species in the collec- 

 tions of the Academy, and labeled as coming from the Florida reefs. 

 The species has also been recorded fi om Cuba. 



Panopaeus Herbstii, var. serrata, De Sausscn. 



Numerous small specimens, both male and female, from under 

 stones on the beach of St. George's Causeway, and at the mouth of 

 Harrington Sound. The specimens vary greatly in color, some be- 

 ing very light, others dark brown, while a few are reddish ; other- 

 wise they are identical in structure. 



The species, described in the Hist, Nat. du Mexique et des Antil- 

 les (Cnistac, p. 16, pi. 1, fig. 7), had previously been recorded from 

 the Bermudas. 

 Lobopilumnis Agassizii, Stimpson. 



One small male, agreeing well with Stimpson's description (Bull. 

 Mus. Comp. Zool., ii, p. 142) except in that it lacks the subhepatic 

 spine. Recorded from Bermuda and Florida. 

 Neptunus hastatus, L. 



(^N. dicanthus.) 



Two small males. 



Geocarcinus lateralis, Frem. 



Numerous large specimens, from the banks and fields near the 

 south shore. We found them specially abundant near the locality 

 known as Spanish Mark or the Chequer Board, and again not far 

 from Penisk)n Pond. The burrows in places extend diagonally three 

 or four feet, or even more, beneath the surface, and the animals, 

 rapidly retreating into these, are frequently difficult of capture. 



This is, doubtless, the species that is referred to by Willemoes 

 Suhm in the Challenger narrative as Gecarcinus lateralis, and is 

 apparently the G. lagostoma (?) described by Miers in the systematic 

 portion of the Challenger Reports (Zoology, XVII, p. 218), in so far 

 as this description applies to the single Bermuda specimen.
