Dr. I'aul Fischer' enumerates 8i species as inhabitants of the 

 " Province magellanique," and to Woodward's list of Falkland shells 

 he adds — Eufluia antantka, Trochus heniatus, Fissiirella pida, 

 Puncturella conica, P. falklandica and Modiolarca pusilla. 



The 'Challenger' expedition collected i8 species at the Falklands. 

 Of these, Calyptrcea pileus, Phot inn la cceriilescens, Trophon liratus, 

 and possibly two unidentified species of Calyptraa and Lamellaria 

 included in the list, are not represented in the Cobb collection. The 

 * Challenger ' specimens were mostly obtained from the " kelp " in 

 from 5 to 12 fathoms. Miss Cobb's shells were all collected on the 

 l)each, but in the majority of cases are in very good condition, and 

 show but slight signs of sea-wear. To several of the shells of Mytihis 

 and Patella some most beautiful specimens of Microporella ciliata, 

 Cribrilina labiosa, C. monoceros, Miicronella tricuspis, Cellepora tiara, 

 C. pundulata and other Bryozoa are attached. We are indebted for 

 these identifications to Miss E. M. Pratt, by whom they have been 

 carefully studied, in connection with another collection of zoological 

 specimens received by the Museum from Mrs Blake, of Hill Cove, 

 Falklands.^ Included in Mrs. Blake's collection are also a number of 

 specimens of Trophon muriciforfnis, Euthria fuscata, Photinula 

 violacea and Fissiirella mexicana, with the animals preserved in spirit, 

 together with several Brachiopods, of which two species, viz. : — 

 Tcrebratella magellanica and T. dorsata, likewise occur in the Cobb 

 collection. 



LLST OF SPECIES. 



Siphonaria lessoni Blainv. — Several typical examples. Recorded 

 also from Chili (I'actel). 



Lachesis euthrioides sp. n. (PI. I., fig. 9). 



Z. testa fusiformi, teniii, Icete castaneo-brun nea, anfradibus septeiit, 

 quorum duobus albatis, apicalibus, ccetcris apud suturas impressis, 

 tuiuidulis, longitudinaliter crassicostulatis, costis ad junduras costu- 

 larum spiralium nodulosis, tiodulis Levibus, nitidissimis ; apertura ardo- 

 rotunda, labro convexo, tenui, canali brevi, curta, i/iargine coluinellari 

 paiillum excavate. Long. 8, lat. 3 tnm. 



Fusoid superficially, this little cancellated shell is undoubtedly a 

 Lachesis. It is of a bright chestnut brown, somewhat shining, fusi- 

 form, seven-whorled, two whorls apical and white, the rest impressed 

 at the sutures, tumid, longitudinally thickly costate, and transversely 

 filo-costulate, shining, noduled at the points of junction. The aper- 

 ture is ovate-rotund, outer lip thin, canal short, columellar margin 

 slightly excavate. Three specimens.
