The interval between the ujntermost anil the uppermost whorls is, however, only I .H mm. The whorls are usually made u]) of but two zooids placed oppciite each other; only the .sixth whorl, re|)ermost whorl of zooids the verrucae measure, however, only mm in lenj^th. The number of zooid body scales in the abaxial rows is usuallv (j-7, rarely H. The other colony from the '"Innolf" .St. 18 consists of two fraf,'ments which are su])]) to be of one set, viz. a 7 mm hir^e, bare axis attached to a stone by a disk, mm in diameter, and a 4(1 mm large, frapmentary colony without base. All the 13 remaining whorls of zooids consist of but two zooids. The intervals between the whorls vary between 3 mm and the size of the verrucae vary between The zooid bodv s5 mm. In a .section of 28 mm there are 11 whorls, the largest interval between two whorls being mm. One of the other colonies is 49 mm high an<l has 13 whorls of zooids, the lowermost whorl being placed 8 mm above the base and the intervals between the rest varying from mm. The number of zooids in the four lowest whorls is 2, in the fifth 3, in the sixth 2 and in the rest of the whorls 3 zooids. The U])])(T zooid whorl is somewhat damaged, the point of axis being bare.
