tips; carpus as long as hand to middle of finger, with small scattered tubercles and two rows of sub- 

 spinous larger ones. Left cheliped similarly formed but with relatively broader, unhooked fingers. 

 Second and tliird legs slender, extending about as far as the chelipeds. Fourth and fifth pairs much 

 reduced, tlie latter turned upward onto the back. 



Measiu'ementsof a male: Length of carapace, 7 mm.;eyestalks, 3 mm.; hand, 8 mm.; width of front, 

 2 mm. 



Pagurus longicarpus is by far the commonest hermit crab of the region and occurs in nearly every 

 locality examined. It is most abundant, however, in the channels whence, by dredging, himdreds 

 may be taken in a few horn's. 



Pagurus corallinus (Benedict). PI. xxx, fig. 4. 



Eupagurus corallinus Benedict, 1892, p. 23. 



Anterior division of carapace subcordate, truncate behind; rostrum obtuse, much produced beyond 

 the roimded, imarmed lateral projections. Eyestalk falling far short of the tip of the antcnnxilary pedun- 

 cle, stout, largest distally; cornea dilated; scale sliarp-pointed and with a prominent subterminal spine. 

 Antennal peduncle about as long as that of the antennule, acicle about equaling eye. Large cheliped 

 with the meros compressed, quadrilateral when seen from the side; carpus a little longer than palm, 

 its upper surface thickly set with sharp spiny granules, its margin with rows of small spines; hand 

 fringed with spines alternately large and small, the spines becoming longer near the tips of the fingers, 

 entire upper surface set with small, slender spines. Smaller cheliped with the meros much compressed; 

 carpus compressed and surmounted by an inner row of small and an outer row of larger spines; hand, 

 wide and compressed; fingers broad and gaping at the base; carpal and propodal articlesof the first and 

 the carpal article of the second walking leg crested with acute spines. 



Color white, the large cheliped blotched with red, the other legs banded with the same color. 



One small specimen about 15 mm. long was dredged by the Fish Hauk in 47 fathoms off Cape 

 Lookout. The large cheliped is missing, but the specimen agrees so perfectly in all that remains with 

 Dr. Benedict's descriptions that his words regarding the missing part have been included in this 

 description. The species has been known previous to this from Key West. 



Pagurus annulipes (Stimpson). PI. xxrx, fig. 12. 



EttpaouTus annulipes Stimpson, 1S60, p. 243; Kingsley, 187S-79, p. 326; Sumner, 1911, p. 666. 



Anterior division of carapace subcordate, truncate behind; rostrum arcuate , lateral angles of front ob- 

 tuse. Eyestalkextendingnearly to tip of antennular peduncle, slightly constricted in the middle, cornea 

 not dilated; scale broad and rounded, but with one or two minute spines on anterior border. Antennal 

 peduncle shorter than that of antennule; acicle slender, hair>-, curved outward. Right cheliped very 

 long, subcy lindrical , moderately and evenly granulate above and finely ciliate; hand somewhat inflated; 

 fingers short and with hooked tips; carpus as long as palm of hand, spinulose along inner margin. Left 

 cheliped much shorter than the right, thickly ciliate and spinulose above; hand shorter than carpus; 

 fingers shorter than palm, weak and slightly gaping. Second and third legs of right side as long as 

 cheliped, ciliate to tlieir tips; those of left side similar, but slightly shorter. Fourth legs much reduced. 

 Fifth pair smaller and carried on dorsal siuiace. 



Measurements of a male: Length of carapace, 3 mm.; eyestalk, 1.2 mm.; hand, 3.5 mm.; width of 

 front, I mm. 



This little hermit crab, while not as abtuidant as P. longkarpjis, is not uncommon on shelly bot- 

 toms in the channels of the harbor and along the coast. When living, its appendages are marked with 

 alternate rings of white and brown. 



Pagurus cokeri Hay. PI. xxx, fig. 2. 



Pagurus cokeri Hay, 1917, p. 73. 



Anterior portion of carapace as long as broad, its anterior margin with three projections of which 

 the middle one is decidedly more advanced and is terminated by a spine about twice as large as the 

 spines of the lateral ones; a little behind tlie frontal margin and parallel with it there is an irregular 

 line of stiff hairs. Ej'estalks short and stout, their length equal to about twice the diameter of the 

 cornea; scale small, its tip spinulose. Peduncle of antennule about one and three-fourths times as
