Abstract
CURTIS has suggested that the initial phase of aggregation of a mixture of cells from Haliclona occulata and cells from Halichondria panicea is not species specific, and he has questioned the general validity of descriptions of species specific aggregation in marine sponges1. Although aggregation is not totally specific in many combinations, it is so in some cases, including the one noted above2,3. I have evidence to support the assertion that species specificity is complete in certain combinations of cells, and to question the applicability of the indirect test for specificity used by Curtis.
