It is characterized by having ciliated funnels of varying size 

 and shape, and often more than one sort in the single specimen. 

 The shape of the funnels is in this group usually quite distinct 

 for each species, though as far as our present knowledge goes 

 none of the genera are characterized by a peculiar shape of funnels. 



The anchors have normally the arms more or less regularly 

 serrate and minute knobs are never found on the vertex. The 

 articulation between anchor and anchor-plate is never made over 

 a bridge, but over some bridge-like irregularities in the surface of 

 the plate. These may be of a very différent shape in different genera 

 and species, but they are of a rather constant shape in the single 

 species. Miliary granules of the skin never in the shape of rosettes, 

 but they are usually bent rods or small perforated plates. The colour 

 of the species of this group is usually pale yellow or brown, very 

 seldom dark brown or blackish, and the size of the specimens is 

 never so large as it may be in the Micrournae. 



The two genera Dactylapta and Anapta most likely belong to 

 respectively Heterournae and Micrournae, but our knowledge of them 

 is for the present too insufficient for saying it definitely. 



The aberrant genus Rhabdomolgus would not seem to be closer 

 related to any of the two groups, and most likely it represents an 

 independent third group.

Genotype: Holothuria maculata Chamisso & Eysenhardt. 



Remarks: In "The Apod. Holoth." Clark writes that the genus 

 Synapta is a monotypic one "(with the type species maculata)", as 

 he supposes the elder "species" which he mentions to be all 

 only one species. This is not so. The collection at hand shows 

 that we have good reasons for regarding Hoi. oceanica Lesson as 

 specifically different from Hoi. maculata Chamisso & Eysenhardt, 

 and that there is nothing that speaks for the identity of oceanica 

 with Synapta mammillosa Eschscholtz.
