LAGANIDAE. 



This family has not hitherto been found on the South African 

 coasts but thei'e is an unmistakable laganid, probably of the following 

 species in the PIETER FAUUE collection. 



LAGANUM DECAGONALE. 



Scutella decagonalis Blainville, 1827. Diet. Sci. Nat.; Scutelle, p. 22!). 

 Laganum decagonale Bell, 1884. ALERT Ech., p. 122. 



This species is still imperfectly known and indubitable specimens 

 are rare. Usually specimens labelled decagonale turn out to be 

 something else and it is so with the specimen in the M. C. Z. col- 

 lection supposed to be from Durban, Natal. This proves on close 

 examination to be a young Cly piaster. However there is a dead 

 Layant/iii test, in poor condition, in the PIETER FAURE collection 

 which seems to be this species; owing to its poor condition, it is 

 however impossible to assert whether it is a Luganum or a Pero- 

 nella. It is 30 mm. long, by some 28 mm. wide and only about 

 4 mm. high; the abactinal system and a large part of the oral 

 surface are missing but enough of the petals remain to warrant 

 referring it to this species. 



P.F. 11740. Off Tugela River, Natal, N.W. by N. 3 / 4 N., 15 miles, 

 36-42 fms. M. 1 specimen; adult, poor. 



FIBULARIIDAE. 



This family also was unknown from South Africa until now. 

 But the PIETER FAURE has taken two specimens of an K<-/iinoct/unutx. 

 which I refer to the following species. 



ECHINOCYAMUS ELEGANS. 



Mazetti, 1895. Mem. Reg. Accad. Sci. Modena, ser. 2, vol. 10, p. 216. 



Of the two specimens taken by the PIETER FAURE, one is a dead 

 test but the other seems to have been living when taken and is 

 densely covered with spines. The dead test is 8'5 mm. long, 6 mm. 

 wide and 2'5 mm. high ; the petals are well-developed with nearly 

 straight and approximately parallel sides; there are 6 or 7 pore- 

 pairs in each area; the genital [tores are much larger than the 

 ocular and are equal to or perhaps exceed the primary tubercles; 

 the mouth is large, somewhat pentogonal, a trifle longer than wide,
