+                supplied, use the faster BigQuery Storage API to fetch rows
+                from BigQuery.
+
+                This method requires the ``pyarrow`` and
+                ``google-cloud-bigquery-storage`` libraries.
+
+                Reading from a specific partition or snapshot is not
+                currently supported by this method.
+
+                **Caution**: There is a known issue reading small anonymous
+                query result tables with the BQ Storage API. When a problem
+                is encountered reading a table, the tabledata.list method
+                from the BigQuery API is used, instead.
+            dtypes (Map[str, Union[str, pandas.Series.dtype]]):
+                Optional. A dictionary of column names pandas ``dtype``s. The
+                provided ``dtype`` is used when constructing the series for
+                the column specified. Otherwise, the default pandas behavior
+                is used.
+
