SECOND YARKAND MISSION. 
There is but one species of the genus Stoliczkaria, the granulate, poreless surface ot 
which distinguishes it from all other forms of the order. 
Syringosph.eria verrucosa, Duncan. Plate I, Pigs. 1 to 3. 
The body is spheroidal in shape, and the surface has numerous large compound wart-like 
or rounded or conical mammiliform eminences on it, and also solitary mammiliform projec- 
tions, as well as small, distant, sharp granules. Numerous minute, shallow, circular pores exist, 
especially on the bases of the verrucose and mammiliform projections, and there are some 
on the surface between them. The largest of these eminences are on the equatorial region- 
The surface between the great and small verrucosities and mammiliform eminences 
supports the majority of the small granulations, and is covered -with closely-packed tubes 
and many tube openings. The tubes run short courses, bend and dip down, and are from 
200 to 3 ^o inch in diameter. They are separated by linear, low projections of dark coloured 
calcite, and very frequently the tube has disappeared and left these limiting products of 
fossilization only. The openings of the tubes at the surface are surrounded by circular rims 
of the dark calcite. 
The top of every mammiliform, conical or verruciform eminence is smooth, and many 
tubes open on the summit and resemble circular patches of a slightly different colour to the 
brownish calcite which environs them. On the sides of the eminences, and reaching around 
and more or less on to the summit (Plate I, Eig. 3), are converging, wavy, linear projections of 
calcite, separated by long broad spaces. The spaces are the remains of tubes, and amongst 
them are wavy tube openings, limited by calcite rims. The pores have tubes around them 
and opening on their shallow floor, and they appear to be parts where the upward growth of 
some radial systems has not been as rapid as the interradial. The height of the body is 1| 
inch, and the breadth is If inch. The diameter of the base of a large compound verrucose 
prominence is inch. In the fossilization of this form the tube-wall is light brown and the 
calcite, which has been infiltrated, is darker brown and smooth. 
String osph m ri a monticularia, Duncan. Plate I, Pigs. 4 to 12 ; Plate III, Pigs. 1, 2, 3, 4, 
8 and 9. 
The body is oblately spheroidal in shape, and the surface has wide-apart, low, rounded, 
compound mammilla) on it, consisting of one large rounded eminence surrounded by many 
smaller ; also solitary, short, flatly rounded mammillae, and very small blunt granules of two of 
three sizes may exist. The pores are very numerous and are small, being found everywhere 
on the surface, and opening directly or obliquely. 
The intermammillate surface is marked mainly with the openings of tubes, and by a 
few T sides of tubes passing for a short distance on the surface and converging on the eminences- 
Most of the tubes are inch in diameter. The mammillae are crowded with tube openings 
which are circular, and often the lighter colour of the substance within the tube is seen 
surrounded by infiltrated calcite. In some specimens the tubes are excessively bent and 
scnicul ate, and they dip down or end suddenly. They surround the pores and open int° 
them. The tubes are crowded, close, and the linear dark calcite often alone remains? 
ndicating the lateral limits of former tubulation.
