The “ocular plates” are devoid of pigment ; but there are numerous 
blue spots on the surface of the body, with a more or less definite 
arrangement. These spots have facetted corneas and pigmented crystal- 
line cones, but no sense-cells nor nervous connection. The blood vascular 
system is stated to be in open communication with the outer world. 
The authors describe a new species, Aslropyga freudenhergi. Two 
parasitic Molluscs, Stilifer lincldce , Thyca entoconcha , n. sp., were found on 
a Linclda.

Complete description of Asthenosoma urens , n. sp., related to A. gruhei. 
Stewart’s organs are very largely developed, and probably of purely 
mechanical significance. Perrier’s “ ovoid gland” proves to be nephridial, 
the ureter opening through the madreporic perforations. There are 
numerous nephridial funnels opening into the coelom. Abstr. in J. R. 
Micr. Soc., Dec. 1888, pp. 956-958, and in Zool. Anz. xi, 1888, p. 115.
