nal section often having a broad summit applied to the vault of 

 the canal and a narrow base, so that it resembles a pedicled 

 mass. This region has numerous transverse folds, so deep in 

 some cases as to merit the name of lamellae (like those in the 

 ruminant's psalterium or " manyplies"). The canal then curves 

 upward Cfrom the posterior pit) and forms a kind of pylorus, 

 with thick walls and deep furrows, and terminates in the intes- 

 tine, into which the part freely projects. The thick rugose 

 intestine, which agrees in structure with that in the ordinary 

 Annelids, terminates in a dorsal anus, with two cirri at the 

 sides inferiorly. 



Some of the examples were laden with ova which in the pre- 

 parations were of a pale orange hue and measured '1524 mm. 

 in diameter. They floated freely in the perivisceral cavity. No 

 evidence existed as to their mode of escape. Other examples 

 seemed to have spawned. Schmarda thought there were special 

 oviducts which opened near the anus, but no trace of these 

 was observed. 



Like the British species at Herm, the South African form 

 would seem to browse on the patches of Halichondria and 

 other sponges which abound under stones between tide-marks ; 

 and there is no wonder therefore that there should be so many 

 interesting homologies between its buccal apparatus and that of 

 such Nudibranchs as Doris tuhercnlata and Doris Johnstom, 

 which follow precisely similar habits, In some examples, 

 moreover, many fragments of crustaceans, numerous portions 

 of cells and avicularia of Polyzoa showed that occasionally the 

 dietary was varied. 



The examples were procured between high and low water- 

 mark at St. James', False Bay.

A further consideration of this form, afforded by Dr.Gilchrist's 

 specimens, inclines me to the belief that Schmarda's species is 

 identical, and it is possible that there is a closer relationship
