unshipped so as to allow of easy transport. This instru- 

 ment worked well on every occasion on which it has been 

 tried. 



We obtained, at about 15 miles N.W. of the bar, 

 a number of specimens of PKdhie aperta, several of the 

 beautiful large Nudibranch, Eolls tricolor, some Holothuri- 

 ans (Caciimaria liijndmanni) and Ascidians, and also dozens 

 of the strange scabbard-like tubes of Onuphls conchylega. 

 Amongst the other worms obtained and since identified 

 by Mr. Hornell, are : — Oicenia jiliformls, N'lcolea venustula, 

 Lumhruiereis fragiUs, Serpula reversa, Thelepus cinciiinatus, 

 Stlienelats limicola, Malmgrenia castanea (on every specimen 

 of Spatangus purpureas) and Hermadion pelluciduni. 



On this expedition, and on the previous " Sf)indrift" trip 

 in July to the same region, Mr. F. Archer took special charge 

 of the testaceous Mollusca, and passed large quantities of 

 the sand and gravel brought up by the dredges through 

 his sieves, in search of the more minute forms. He has 

 now found ten species which were not recorded in the Eeport 

 on the Mollusca in the first volume of our Fauna, includ- 

 ing : — Pa)tdora hice(piivalvis, Vemis chione, Fwicturella 

 noachhia, and Adeorbis suhcarinatus. 



The mud dred<red on this trip has been examined for 

 Foraminifera by Mr. F. G. Pearcey and Mr. G. W. Chaster, 

 and has yielded 63 species (see Appendix A, p. 40.) The 

 Zoophytes of this expedition, and of the " Albert" trip on 

 July 5th, have been examined partly by Miss Thornely and 

 partly in the Zoological Laboratory of University College 

 by Mr. W. J. Halls. The " Spindrift " forms include the 

 following additions to our list : — Hydra nthea margarica, 

 Blmerla veatita, Caiupanalaria hhickslf, Gonotliyrcea gracilis 

 and Aglacpheuia tuhaUfera. The surface life on this occa- 

 sion (Sept. 27th) was very abundant, the tow-nets bring- 

 ing up great quantities of Copepoda, &c. Amongst these
