Thus while 152 comatulids are actually known to live along the shore, 93 

 more undoubtedly also occur there, so that we are justified in assuming 245 littoral 

 species among the forms already described. 



Of these 245 species 226 are from the Indo-Pacific region (including north-

 and Brazil, 6 are from the northeastern Atlantic (north of the Gulf of Guinea), 

 and 4 are from southern Australia. 



Species found swimming at the surface. — The young of two comatulids, Coman- 

 thus parvicirra and Dorometra n^na, have been taken swimming at the surface in
