ability, and give us some satisfactory and reliable information. In the 

 dredging (Station 22) at 718 fathoms, Mr. Norman reports new species 

 of Crustacea belonging to four genera. 



19. July 27th. Dredged a few miles north of Cape St. Vincent, in 292 

 and 374 fathoms (Stations 24, 25). Ground rocky ; and in the evening a 

 dredge, with 400 fathoms of 3-inch rope, was unavoidably lost. The last 

 haul yielded two Siliceous or Vitreous Sponges of an enormous size, one of 

 them measuring nearly 3 feet in diameter at the top, of the kind called 

 "Neptune's Cup" (Askonema Setubalense, Kent), besides that lovely 

 sponge, Aphrocallistes Bocagei. The Mollusca were mainly northern, and 

 included fresh-looking fragments of the gigantic Lima excavata, besides 

 Limopsis minuta (distinct from L. borealis), Pecchiolia acuticostata, P. 

 granulata, Trochus suturalis, and Pleurotoma hispidula or decussata, all of 

 which are Sicilian fossils. Two undescribed species of Crustacea, which Mr. 

 Norman proposes to name Amathia Jeffrey si and Ethusa mirabilis, were 

 here obtained. — At night we steamed slowly south, and doubled Cape St. 

 Vincent. The electric telegraph-cable between Falmouth and Gibraltar 

 sadly hampered our movements in this part of the cruise, by occupying 

 the ground which we were most desirous of exploring. It was not con- 

 sidered safe to dredge within eight or ten miles on either side of it. This 

 was a serious drawback ; since it obliged us to dredge either in water which 

 is too deep for systematic or continued exploration, or in comparatively 

 shallow water near the coast, where the ground is rocky and the dredge 

 liable to be lost. 



20. July 28th. Dredged several times off Cape Sagres in from 45 to 

 58 fathoms. Fauna southern. Venus multilamella, Tellina compressa, 

 and Halia Priamus occurred living ; and Dr. M'Intosh says that two 

 Annelids (Glycera capitata and Pr axilla prcetermissa) had not been 

 hitherto observed south of the track in last year's expedition. The sea 

 being rough and wind high, we anchored off Lagos. 



21. July 29th. Steamed south, and dredged in 364 and 322 fathoms 

 (Stations 26, 27). The water was of an indigo-blue colour. Weather 

 fine, but rather windy. For the first dredging 700 fathoms of rope were 

 payed out, and two weights of 100 lbs. were attached at 350 fathoms 

 from the dredge. The Mollusca comprised some of the new and remark- 

 able species procured in Station 16 (994 fathoms) and other dredgings, as 

 well as Terebratula vitrea, T. cranium, Pholadomya sp. n., Trochus ama- 

 bilis, Pyramidella plicosa (Belgian and Coralline Crag), Tylodina Dubeni 

 (Norwegian), Cancellaria mitrceformis, C. subangulosa (both Coralline 

 Crag), Pleurotoma galerita, and Actceonpusillus. The Crustacea of most 

 interest were Pagurus platycheles (sp. n.), and an undescribed species of 

 Munna. The Corals were Flabellum distinctum (the same as in Station 

 16) and Amphihelia oculata. The Hydrozoa in 364 fathoms included a 

 new and beautiful species of Plumularia. But the most remarkable 

 novelty here obtained was a large collection of thin sandy disks, from 0*3 to
