REPORT ON THE BRACHIOPODA. 67 



near Noumea, New Caledonia ; also at Aneiteum, New Hebrides ; and at Isle Nou, New 

 Caledonia; and lastly, at the Sandwich' Islands, whence it has been often quoted. 



Mr Brazier tells me also that he has dredged in Port Jackson for the last twenty-five 

 years, and never found a specimen of Terehratidina until quite lately, when he went to 

 what he calls a new field, where one can only go when the wind is either north or north- ■ 

 east, with the sea smooth, so as to get close in to the rocks with a boat. The locality is 

 Inner North Head, ofi" Port Jackson, and the Old Man's Hat Point, 7 to 8 fathoms, rocks, 

 stones, broken shells, and sandy mud. The first day he went, in washing out the 

 dredgings, he obtained a specimen dead, and as black as ink, caused by bein^- in mud. 

 He examined it closely, and seeing that he had never found the like before in Port 

 Jackson, continued dredging all day, and was rewarded with three more specimens in 

 good condition. Mr Brazier believes this shell to be a dwarfed variety of Terebratulina 

 cancellata, Koch. 



Through the kindness of Mr Dall I have been able to examine the types of Gould's 

 Terebratella pulvinata ?ia.d. Terehratella ]^atagonica from the State Museum, Washington. 

 I much fear that the first is no more than a young smooth specimen of Terehratella dor- 

 sata, while the second appears to me to be a young Magasella (Ter.) Jlexuosa, King. I 

 also arrived at the conclusion, after examination of the type specimens of Cutella rubro- 

 tincta, DaU, and Cistella ardiUarmn and Cistella schrammi, Crosse, that all these three 

 are synonyms of my Cistella barrettiana of which the type is in the Museum at Cam- 

 bridge, and I believe that Mr Dall is disposed to take a similar view. Cistella lutea, 

 DaU, cannot be well distinguished externally from Cistella barrettiana, but its median 

 septum presents certain peculiarities which render it possible that it may be a distinct 

 species. 



Discina tenuis and Discina losvis, Sow., evidently belong to a single species, and it 

 may also remain a question for further consideration whether the large, square, oblong 

 examples of Lingida from Moreton Bay, Australia, to which L. Reeve has given the name 

 tumidula (see specimens in British Museum), may not be mere variations in shape of 

 the more elongated Lingida murphiana that occurs in the same locality. It appears 

 quite evident that on further study, with the aid of more ample material, the number of 

 so-termed species of Lingula and Glottidia will have to be reduced. Unfortunately, of 

 several of them, we are acquainted with one or two individuals only, and upon such 

 scanty and insufiicient material it is impossible to arrive at satisfactory conclusions. 

 This remark will apply equally well to a certain number of the species belonging to other 

 genera ; and there is every hope that these matters -wall, with time, be set right by the 

 numerous dredging expeditions that are now being carried on by nearly all the maritime 

 nations.
