Following the groups as above arranged, there is a gradual change observable from the purely actinoid or radial to the bilateral type, which is most developed in the SPAT,LYGIME, and according to the arrangement previously adopted in the present series of monographs of South Indian cretaceous Invertebrata, I shall begin the detailed account with the last-named family The distribution of the specie [...] In the first group, which is by some authors also separated as a special family under the name _Ean/Nocara-DiE, the ambulacra are perfectly open towards the periphery of the test, with the exception of the impair one, the other four lie flat on the surface, and the apical apparatus (except in Stenoni& is elongated, the anterior genital plates being sometimes quite separate by intervening ocular p [...] All the ambulacra are deeply impressed, the anterior a little less than the others, but the furrow passes over the periphery on to the lower side ; its pores are small, composed of about twelve distant pairs from the centre to the fasciole ; the lateral ambulacra are nearly closed, the anterior series of pairs of pores bending conspicuously towards the middle line. [...] The cheeks are rounded ; the aperture about one-fifth of the length of the test distant from the anterior end ; the lower lip is very prominent and granular ; the post-oral space much contracted near the aperture, coarsely tubercular. [...] The height of the test somewhat varies, being usually equal to the distance between the anterior lip of the aperture and the anal end; in the most depressed and one of the smallest specimens it only equals the distance from the lower lip to the posterior end.
