Arenicola cristata 105 



taken by him in Saldanha Bay, a full description and diagnosis of 

 the species were prepared (1910). 



HABITAT, SIZE, COLOUR. The b&bifotofA.loveniis similar to that 

 of A. marina, the specimens found in Saldanha Bay were a foot or 

 so beneath the surface. 



The type specimen is 405 mm. long, the tail being 155 mm. 

 The specimen figured on PL Til closely approaches the type in length 

 (385 mm.), and in the proportion of body to tail, but is rather stouter. 



There are no observations available regarding the colour of this 

 species in life. The appearance of the preserved specimens suggests 

 that, when living, their colour would be similar to that of examples 

 of A. marina of light or medium tone. 



REMARKS ON THE TYPE SPECIMEN. The type specimen possesses 

 an additional chaetiferous, but abranchiate segment, in which, however, 

 only notopodia smaller than those of the preceding segments are 

 present (Fig. 44, p. 104). Kinberg's figure * and description are correct 

 in regard to this twentieth segment, but, as the type specimen is 

 abnormal in this respect, the diagnosis of the species has been emended 

 so as to state that nineteen chaetiferous segments are present. 



DISTRIBUTION. Arenicola loveni has been found only in three 

 places, namely, Port Natal, near Durban, Saldanha Bay and False 

 Bay, Cape Colony. 



Type specimen in Kiksinuseum, Stockholm.

1 The difference in the sculpturing of the skin of the pre -branchial and 

 branchial regions is not marked and abrupt as shown in Kinberg's figure. 

 PI. Ill, Fig. 9, accurately represents the sculpturing of the epidermis.
