Crisia elongata Milne-Edwards, 1838:203. 

 Crisia elongata, Harmer, 1915:96 (synonymy). 

 Crisia elongata, Canu and Bassler, 1928:157. 

 Crisia elongata, Osburn, 1940:328; 1947:3. 



Zoarium with long, slender, sprawling branches ; the internodes elon- 

 gate, usually with about 14 to 16 zoids but ranging from 6 to 30 or 

 more, the joints of both branches and radicles jet black (brownish in 

 younger areas of the colony). The tubules of the zooecia are embedded 

 and their outlines scarcely visible, their peristomes short and turned 

 sharply forward, with usually a small denticle behind the distal border. 



The ovicell is situated usually near the middle of an internode, short, 

 suddenly and broadly inflated ; the ooeciostome is little or not at all 

 elevated and its pore is a transverse slit. 



Our rather scanty material agrees well with Harmer's excellent de- 

 scription (1915:96) and with specimens from the West Indian region. 

 It is my opinion that the C. eburnea forma denticulata of Smitt (1872: 

 4), the C. denticulata of Osburn (1914:185) and the C. denticulata of 

 Canu and Bassler (1928:156), all from the Gulf of Mexico and the 

 West Indian region, should be referred to C. elongata. 



Hancock Station, 277-34, ofiE Isabel Island, Gulf of California, 21° 

 5r35''N, 105°30'W, at 10-25 fms. It is apparently a circumtropical 

 species.

The zoarium is rather stiff and straggling in appearance, the inter- 

 nodes varying greatly from 7 to more than 30 zooecia. The joints are 

 colorless or slightly brownish in older zoaria. The branches are rather 

 numerous, 3 or 4 to an internode, the basis rami usually exserted but 

 sometimes short, always a branch immediately above the top of the 

 ovicell. 



The ovicell is usually situated low in the internode, most frequently 

 the third member of the internode; elongate, expanding rapidly near 

 the base and maintaining the same width for most of its length ; con- 

 siderably inflated and adnate to the internode for its full length. The
