Haplophragmium, Reuss. 



H. cassis, Parker. This is one of the most striking and unex- 

 pected of the discoveries made among the estuarine forms. The 

 test is coarsely arenaceous, and in contour is isomorphic with the 

 hyaline species, Cristellaria crepidula. It is a very rare species. 

 Mr. Brady states (" Challenger Report ") that it is peculiar to 

 the shallow water areas of the Northern seas. Its known dis- 

 tribution only comprises three localities, viz., Gaspe Bay, at the 

 mouth of the St. Lawrence, 16 faths. ; Lievdy Harbour, Disco, 

 Greenland, 5 to 20 faths. ; and Deva Bay, Spitzbergen, 7 faths. 

 The occurrence of so rare a form at a spot very remote from its 

 known range of distribution is of peculiar interest. A few speci- 

 mens v/ere taken on seaweed bottom, but it is moderately com- 

 mon on mud-banks nearer shore. 



II. agglutinans, d'Orb. Spiralline in earlier segments and 

 rectilinear in the later growths. Coarsely arenaceous. Very 

 widely distributed, but it is more commonly found in deep water 

 than in shallows. Rather scarce in brackish pool near Birken- 

 head, and moderately common in small creeks near Pinery on 

 sandy bottoms. 



Trochammina, Parker and Jones. 



T. injlata, Montagu. A species of limited range, and very 

 characteristic of shallow and brackish water conditions. It is 

 found inhabiting the estuaries of Britain, and the only " Chal- 

 lenger"- records are north-east shores of Bay of Biscay, and 

 south-east portion of coast of Spain. This is, therefore, the first 

 record of this species for the Southern Hemisphere. On seaweed 

 ground, North Arm ; brackish pool, Birkenhead ; and small creek, 

 near Pinery. 



T. squaraata, Jones and Parker. The habit of this species is 

 more distinctly marine than the preceding, and extends to mode- 

 rate depths. It has a somewhat wider range of distribution than 

 T. infiata, although by no means common. Three or four exam- 

 ples of small size were obtained from the mud-banks, North Arm. 



Clavulina, dOrhigny. 



C. C07njnunis, d'Orbigny. A straight and slightly-tapering 

 f oraminifer, constructed of fine sand grains. It is not uncommon 

 in the South Pacific, occurs on west coast of New Zealand, and 

 ranges to the Antarctic ice-sheet. An interesting form in our 

 estuarine fauna, as it usually frequents deeper water. Mode- 

 rately common in brackish pool at Birkenhead. Rare in creeks, 

 near Pinery.
