T h 



e collection includes the following species : 



i. Polypus schultgei n. sp. 

 2. Moschites nigra n. sp. 



3. Loligo reynaudi. 



4. Sepia tuberculata. 



The first two species are additions to our knowledge ; the third and fourth are of interest because, 

 although one of them was described seventy years and the other more than a Century ago, they do not seem 

 to have been met with by any traveller for very many years. I have taken advantage of their occurrence 

 in this collection to give a füll description, with a few necessary figures. 



All the specimens were taken in the Lüderitzbucht, Angra Pequena, German South West Africa, 

 among the rocks in shallow water. 



I am indebted to the Rev. H. M. Gwatkin for mounting examples of the Radulae, to Miss Mary 

 Brockington for some of the drawings and to Mr. J. T. Wadsworth for preparing sections, and I desire 

 here to tender my thanks to these collaborators. 



Polypus schiiltsei, n. sp. 



Locality: Angra Pequena. One specimen, $ (H 1365) 1 ). 



The Body is comparatively small and ovoid, but so distorted that it is impossible to give any 

 more detailed description. The siphon has been forcibly refiexed, but is small, and in its natural position, 

 would not have reached more than one third of the distance towards 

 the margin of the umbrella. 



The Head has been compressed out of all recognition by a 

 ligature of some kind having been tied tightly round the junction of 

 the head with the roots of the arms. 



The Arms (PI. Va, Fig. 1) are stout and well developed, but 

 so many of them seem to have been injured in one way or another 

 that it is difficult to give any account, of what their relative lengths 

 would be under normal conditions. 



The Umbrella is well developed; between the dorsal arms, it reaches up to the I4th sucker. It 

 becomes gradually less developed between the other arms proceeding towards the ventral surface and is 

 narrowest between the ventral pair. The suckers vary greatly in diameter, much enlarged ones being 

 found on all the upper arms. On the right ventral arm they increase gradually for about the first quarter 

 of the arm and then diminish. On the third right arm the increase in size is much more rapid, the eighth 

 sucker attaining a diameter of abut 1 cm. On the second right arm the largest sucker attains a diameter 

 of 11 mm, whilst on the dorsal arms the largest suckers are 12 mm in diameter in the contracted condition,
