NO. 1 TAYLOR : PACIFIC MARINE ALGAE 27 



remnants of electrical and mechanical equipment, now all abandoned. 

 Shore collecting here did not amount to much. Dredging, however, was 

 excellent here and yielded many things, which with other I. Santa Maria 

 dredging will be discussed below. 



At Black Beach Anchorage the sand was, as the name would indicate, 

 veiy dark blackish brown, a surprising contrast with the brilliant white 

 coral sand found at many of our stops. The beach was backed by an 

 abandoned clearing made attractive by numerous Parkinsonia trees. Rocky 

 outcrops ran down into the sea, and the shore collecting done from this 

 center was very productive indeed. As we made two stops at I. Santa 

 Maria of some days' duration, far more serious work could be done there 

 than at any other place visited, and the results reflect the better oppor- 

 tunity. Repeated visits to the rocky pools and ledges were made at low 

 tide and many collections secured. Although the male sea lions did occa- 

 sionally chase us away for a time, the females and young ones, which 

 commonly were present, did not as a rule pay any attention, or swam 

 away. On the high rocks spectacular Cereus and Opuntia trees were 

 prominent features of the vegetation, with various large spiny shrubs 

 below. In the intertidal zone, and within reach at low tide, the variety of 

 algae was great. It was possible here to study relatively sheltered pools, 

 and rocky points exposed to considerable surf. The dominant algal species 

 appeared to be Blossevillea galapagensis, a notable fucoid endemic known 

 from the time of the Vettor Pisani Expedition. This grew high on the lit- 

 toral rocks in great abundance. Also common were Ectocarpus tomentosus, 

 Padina Durvillaeij Gelidium Hancockii (new), Lithophyllum Farlowii, 

 Spatoglossurn veleroae (new), Amphiroa peruana, A. dimorpha, Caulerpa 

 racemosa, Codium isabelae (new), Pachymenia saxicola (new), Ty lotus 

 ecuadoreanus (new, from a very exposed situation in the heavy surf), 

 Herpophyllon coalescens, the first collection since the type was brought in 

 by the Hopkins-Stanford Expedition, and a very curious endemic, and 

 finally the morphologically interesting Dendrymenia flabellifolia, a more 

 southern plant. The list of relatively scanty items, including several nov- 

 elties, is far too long to cite. 



Dredgings ofif Post Office Bay and Black Beach Anchorage may 

 properly be considered together. The depths ranged from 6 to 183 meters, 

 but the greatest depths were on a sandy bottom and not productive of 

 algae. However, effective dredging to 55 meters was done and a large 

 assortment of good deep-water marine algae secured, far too large to 

 adequately discuss here and by far the best of the expedition. Of presumed 

 novelties over a score of types came from this series of hauls. There are 

 too many to designate even all the genera, but particularly striking are
