In a previous publication in this journal, Finks (1955) reported the discovery of two sponge specimens containing external molds of the conulariid Paraconularia leonardensis (Finks). The sponges were collected from the Permian Leonard and Cherry Canyon Formations, west Texas (Finks, 1955,1960). As argued by Finks (1955), the conulariids contained in the sponges probably were sessile, and two conulariids in one of the sponges may have been directly attached to the sponge in life. These interpretations are corroborated by evidence documented by several other authors, most notably Sinclair (1948) and Babcock et al. (1987).
