Porcellana sayana . Kingsley, Proc. Acad. Nat. Sci. Phila., p. 407, 1879. 
The front is triangular and emarginate on the sides; it is well separated from the lateral teeth at 
the angles of the orbits by wide and moderately deep incisions. The carapace is longer than wide. 
There is a shoulder where the cervical groove meets the side. The surface is minutely rugose. The 
chelipeds are short, curved, and bent; inner distal angle of merus and proximal inner angle of carpus 
produced, forming lobes. There is a fringe of long hair on the outer margin of the hands. 
This species can readily be distinguished from any other porcellanid of the region by the 
numerous white spots on a red ground, both on the carapace and feet. A favorite place for this crab 
is in the spire of a large univalve containing a hermit crab.

Porcellana stimpsoni A. Milne-Ed wards. 
Porcellana stimpsoni X. Milne-Edwards, Bull. Mus. Comp. Zool., vm, p. 35, 1880-81. 
Not examined “by the side of P. sayana. The carapace is wider. Its front is less advanced; the 
median point is rounded, lobiform, and it does not pass the inner angles of the eye. The anterior 
feet are smooth and are not fringed with hair as on P. sayana.” 
Dredged by the Blake. 
Porcellana sigsbeiana A. Milne-Edwards. 
Porcellana sigsbeiana A. Milne-Edwards, Bull. Mus. Comp. Zool., vm, p. 53, 1880-81. 
This species is much the largest of the porcellanids of the region and comes from deeper water, 
ranging from 25 to 175 fathoms. The front is deeply tridentate; the rostral projection extends beyond 
and is much larger than the lateral (eeth. The lateral margin of the carapace is thin, produced, and 
is slightly turned upward. The chelipeds are long; to the eye they are smooth and glabrous; under 
a lens the surface is broken by minute rugie composed of small granules. The color markings on the 
carapace, in the alcoholic specimens, consist of lines running longitudinally. 
Dredged by the Blake. 
Porcellana soriata Say. 
Porcellana soriata Say, Jour. Acad. Nat. Sci. Phila., i, p. 456, 1818. 
Pisidia soda Leach, Die. Sci. Nat., xvm, p. 54, 1820. 
Porcellana sociata Gibbes, Proc. Am. Assoc. Adv. Sci., in, p. 190, 1850. Kingsley, Proc. Ac. Nat. Sci. Phila., xxxi, p. 407, 1879. 
The front appears rounded when seen from above, tridentate from before; the rostral tooth is 
but little larger than the lateral teeth. The areolations of the carapace are well marked, some are 
inclined to be tubercular. The ambulatory legs are hairy; the chelipeds are very tuberculose; the 
tubercles are large and granulated; on the carpus they are placed without regularity, while on the 
hands they are in more or less well-defined rows; the lower margin of the hands are fringed with hair. 
It seems necessary to restore Say’s name soriata, which was dropped, perhaps, on account of its 
form or with the belief that the letter c was intended where r was used. Dr. Gill thinks that the 
name was suggested to Say by the fact that the aggregations of granules into tubercles on the chelipeds 
resemble the “sori” of ferns. The word sorus itself, he adds, is derived from the Greek doopos, 
meaning, primitively, a “heap of corn.” With this derivation the name will apply to the species 
much better than sociata, as the tubercles look like heaps of granules.

Porcellana pilosa H. M. Edwards. Plate 3, fig. 11. 
Porcellana pilosa H. M. Edwards, Hist. Nat. des Crust., n, p.253; Kingsley, Proc. Acad. Nat. Sci. Phila., p. 106, 1879. 
Readily distinguished from all other porcellanids of the West Indian region by the short, stout 
bristles on all of the feet in connection with the group of white tubercles on proximal portion of carpus. 
The median projection of the front is rounded and but little in advance of those at angles of the eyes.
