20 ALLAN HANCOCK ATLANTIC EXPEDITION REPORT 



Scrupocellaria bertholetti (Audoviin), 1926 



Marcus 1938:24. Osburn 1940:386. 



A very widely distributed species in warmer waters. Osburn recorded 

 ft from Porto Rico and the Tortugas Islands, and Marcus from Brazil. 



Distribution. — Stations A14-39, A18-39, and At504. These stations 

 place the locations at Cape la Vela, Colombia, and Aruba Island at 21 to 

 71 fms. 



Scrupocellaria frondis Kirkpatrick, 1890 



Osburn 1940: 387 footnote. Hastings 1943: 361. 



This species is remarkable for the large, broad, cervicorn spine with 

 4 or 5 points, which bends across the upper part of the aperture distal to 

 the scutum. This character, with the rounded scutum, renders it un- 

 mistakable in the West Indian fauna. An excellent discussion of the 

 species, with its known distribution, is given by Dr. Anna B. Hastings 

 (loc. cit.J. It has been taken at Fernando Noronha, Pernambuco, Ascen- 

 sion and the Tortugas Islands, all in the Atlantic. 



The present material consists of 7 small colonies, several of them 

 with ovicells. One was attached to the flat surface of an alga, the others 

 to small branching corallines. 



Distribution. — Station At505, Aruba Island at 23 fms. 



Scrupocellaria harmeri, new species 

 Plate 3, Figs. 1-2 



Zoarium loosely spreading, the branches narrow, the internodes with 

 3 to 6 zooecia in a series; joint crossing the outer zooecium just proximal 

 to the opesia. 



Zooecia slender, elongate (length 0.40 mm, width 0.13 mm, narrowed 

 to about 0.09 at the proximal end), nearly straight, a little incurved on 

 the outer border. Opesia decidedly less than one-half of the frontal length, 

 ovoid, slightly constricted distally, with a broad conspicuous cryptocyst. 

 Scutum ovate, upper lobe small, attached well above the middle of the 

 opesia, without alcicorn decoration, wanting on many of the zooecia. 

 Spines 3 outer and 1 or 2 inner, moderately developed. 



Frontal avicularia very small, with triangular mandible, wanting on 

 most of the zooecia. Lateral avicularia large and prominent, on all of 

 the zooecia, rostrum and triangular mandible both hooked at the tip.
