[voL. xiir. 
Pos. angusta, Hau. Tliotigh it seems that there are several varieties, if not species, 
amongst the nnmerons sxDecimens obtained, I prefer to include them for the 
present under one collective name. 
Otoceeas woodwaedi, nov, spec. Plato I, figs. 4 & 6, and Plate II. 
Shell involute, with very deep umbilicus, with rapidly increasing outer 
whorls. The part of the shell nearest the umbilicus bulged out into an ear-like 
shape, giving the section of the shell (Plate I, fig 4a,) a more or less rhom- 
boidal asjject. 
It is very probable that the last whorl in adult individuals covered and 
enclosed the entire shell. In all the specimens which I collected there -is a 
tendency to enlarge the latter whorls at the expense of the umbilicus. The 
sides of the shell are only slightly ciirved and slope towards the sharp knife-like 
siphonal side enclosing an angle of about 67°. The compressed siphonal side 
is one of the most characteristic features of this sjiecios. In one of the adult 
specimens (Plate I, fig. 4), this piart of the shell has quite the ap]3carance of a 
shar}D knife, and only a faint indication of a tlmec-edged termination is visible; 
whereas in some of the younger specimens (Plate II, figs. I and .3) and even in the 
older form (Plate II, fig. 2«) the trijmrtite character of the siphonal side is strong¬ 
ly marked. This character alone would stamp this species as belonging to Uun- 
garites, Mojs.,^ of which H. soafiitiformis, Hau.,^ and H. zalaonsis, Bockh.,^ are 
the types, but the shape of the ear-like prolongation of the sides of the shell 
near the region of the second side-lobes is a character entirely absent in the 
Austrian genus. A line connecting the ear-like jrrolongations of the sides, or, 
in other -words, the second side-lobes, wall intersect the median xdaue in a point 
from which to the sixihonal margin of the jjroecding whorl is about the third 
of the entire distance between the ^joint of intersection and the siphonal margin 
of the outer shell. A vertical ju’ojection of the inner margin of the first lateral 
saddle to the median piano will intersect that jrlane in the six)hon of the j)re- 
(jeding whorl. 
From Plate I, fig. 4(t, it will bo seen that the irroportion in the increase of 
lateral exjiansion of the last whorl increases rapiidly at the expense of the increase 
to the height of the shell, and it is not at all imxu’obable that, as I said above, 
the final chamber inclosed nearly the Avholo of the shell in adult specimens, 
which character is indicated in fig. 3 of Plate II, which shows the almost vertical 
sides of the umbilicus, but since drawing the plates I have worked out of some 
blocks of stone the fragment of a larger specimen, showing part of the last 
chamber with the umbilicus. The latter is very narrow and closing in towards 
the outer side. The shell is extremely thick near the ear-like prolongation in 
the umbilical region and covered -with wrinkles. The shell is covered -with fine 
wavy lines of growth S-shaped, slightly bent forward near the siphonal margin. 
The lobes show some variation, mainly in the auxiliary ones, but these in¬ 
crease in number with the successive whorls in the same specimen. As shown in
