" May 30, 1911 " (off Key West). "... 6 a. m We take a 



position about where we failed yesterday in 50 fathoms, using the 

 medium dredge for several unsuccessful hauls ; then we bend on ' old 

 Sampson ' (our largest and heaviest dredge) and lower away. This 

 time the bag comes up full of large broken shells, mostly Pectens 

 and large bivalves all dead and worn, from shallow water ; this is no 

 good at all. Run out to 90 fathoms and make three very good hauls 

 on the edge of the Pourtales Plateau. The features of the bag are 

 some very interesting Murices of the Pteronotus group with wide 

 foliated varices and quite suggestive of certain Pacific Coast species. 

 Also Murex heauii, a very fine species of that fine genus. We especi- 

 ally rejoice over these Murices for with them added to our records 

 we have nearly completed the list of Atlantic Coast Muricidae. 

 Valuta dohrni, Calliostoma hairdii, a superb Fusvs eucosmia twice 

 the size of any specimens I have ever seen. It nearly took our 

 breath away. . . . The clearness of the water here is most striking. 

 We always watch over the side of the boat to see who will first dis- 

 tinguish the dredge as it is being hauled up by the power winch. 

 Its white skirts begin flashing so far below the surface we have been 

 speculating upon the actual distance. We measured the rope to-day 

 and found that we could actually see the dredge at 104 feet." 



"June 11, 1911" (Key West). "In bagging the dried siftings 

 of a haul made yesterday in 90 fathoms, we made the splendid dis- 

 covery of a Haliotis. This is probably Haliotis poiirtalesii of Dall, 

 described by him from memory of the unique specimen which was 

 destroyed in the Chicago fire. Pourtales obtained his specimen 

 right about here. This one just taken is now the only specimen ' in 

 captivity.' We are quite excited about it . . . alas, we need all 

 the cheer we can find, for the loss of our two carefully designed traps 

 and 'old Sampson,' all in one day, has cast a gloom upon us . . . 

 61 fathoms, a fragment, though brightly colored, ot Valuta junonia, 

 the first in our records." 



" June 6, 1911 " (Key West). "... proceeding out we meet a 

 stiff wind with swell and a nasty chop on top, but we try out a few
