THE VOYAGE OF H.M.S. CHALLENGER. 
in Soldani’s Testaceographia. 1 As lias been shown elsewhere, the name in its original 
application was needless, “ the five figures ” referred to by d’Orbigny being “ all Uvigerinci 
pygmcea, not differing more amongst themselves than may be seen in any batch of recent 
specimens ;” 2 there is, therefore, no reason why it should not be retained for the particular 
form described by the English authors. 
Sagrina nodosa furnishes the morphological links connecting Sagrina striata, Sch wager, 
with the typical Uvigerince. The test is proportionately stouter and the Uvigerine section 
is relatively larger than in Schwager’s species, and the chambers of the uniserial portion 
are less inflated and more compactly fitted. The drawing (PL CXIY. fig. 18) represents a 
specimen with fewer Uvigerine segments than the test usually possesses, whilst in Parker 
and Jones’s illustration, on the other hand, almost the entire shell is spirally arranged, 
and there are only two uniserial chambers. Between these extremes every variety of 
conformation is to be found. 
Sagrina nodosa is by no means a common form : so far as the Challenger collections 
are concerned, it only appears at one locality, — off the Cape of Good Hope, depth 150 
fathoms. Otherwise it has been reported from the Mediterranean and from the Italian 
Tertiaries.

This species differs from the allied Sagrina raphanus in the subglobular form of the 
segments and the superficial ornament of delicate, raised, longitudinal lines. The 
illustration (fig. 25) represents an average example of the species as found in the living 
condition. I have never met with recent specimens exhibiting the beautiful symmetry 
of contour and regularity of striation shown in the original drawing, though the salient 
morphological characters correspond pretty closely in other ways. 
Hr. Schwager draws attention to the general similarity of his specimens to the 
Nodosaria striatissima of Stache (Novara-Exped., geol. Theil, vol. i. pt. 2, p. 198, pi. xxii. 
fig. 25, a-f) ; and, after careful examination of the drawings of the latter form, I have 
little doubt that most if not the whole of the fossils, figured under that name belong in 
reality to the present species, notwithstanding the apparent absence of Uvigerine initial 
segments. 
Sagrina striata has been obtained as follows : — off the coast of South America, south
