408 MR. F. CHAPMAN ON THE 
Note on New Species from the Sands of the Reef-slope. 
SPIROLOCULINA PARVULA, sp. nov. (Pl. 36. fig. 5.) 
Test ovate, complanate, extremities produced. Oral extremity 
usually terminating in a tubular prolongation, with an everted 
rim. Segments few and broad, marked by salient sutural edges ; 
surface of segments more or less excavated. JLength °35 mm. 
Off Tutanga, 200 fathoms; frequent. 
Affinities—This form seems to be intermediate between 
Brady’s Spiroloculina limbata var.* and Terquem’s S. impressat. 
From the former of these it differs chiefly in its smaller size and 
spouted orifice, and from the latter in having a more circularly 
ovate outline. 
OPHTHALMIDIUM CORNU, sp. nov. (PI. 36. fig. 6.) 
Test ovate, compressed; the early spiral tube small and neatly 
coiled; the later Spiroloculine segments large and few in number, 
and partly concealing the spiral portion of the shell. The later 
segments have a thin peripheral flange, as in O. inconstans. 
Aperture trumpet-shaped and opening towards one side of the 
test. Length of test °5 mm. or less. 
Off Tutanga, 50-60 fathoms ; rare. 
HaplopHRAGMIuM cassis (Parker). (PI. 36. tig. 8.) 
Lituola cassis, Parker, 1870 (in Dawson’s paper), Canad. Nat. n. s. 
VOL avn! Lid sp. LOO; ne. 38 
Haplophragmium cassis (Parker), Brady, 1884, Rep. Chall. vol. ix. 
p. 304, pl. xxxiii. figs. 17-19. 
The tendency in our specimens is for the oblique chambers to 
be subdivided, giving an appearance like that of Casszdulina to 
the test. The species is, however, extremely variable. Until 
Millett recorded this species from the Malay Archipelago, it 
appeared to be confined to the colder areas of northern seas. 
W. of Tutanga, 35 fathoms; very rare. 
HAPLOPHRAGMIUM 'TESSELATUM, sp. nov. (PI. 36. fig. 9.) 
Test moderately thin, compressed, the spiral commencement 
subcircular in outline, septation very obscure; later chambers 
few, constricted at the septal lines, and arranged im an irregular 
rectilineal manner. Surface of shell marked by polygonal areole. 
Length of test 1°3 mm.
